Prepare the generator for more struct fields that have nested "dynamic
arrays" with a hardcoded size of `1` (effectively arrays with pointers
to single objects) in `vk.xml`s `len` attribute. These structs are
introduced by `VK_EXT_opacity_micromap` in 1.3.230.

* ash: Add `const STRUCTURE_TYPE` to all Vulkan structures for matching with `match_struct!` macro
In Vulkan layers extracing a structure based on its `s_type` is a common
operation, but comparing against an enum value and subsequently casting
to the right type is verbose and error-prone.
By generating a `const STRUCTURE_TYPE` with the given value for every
Vulkan structure it becomes possible to implement a macro that abstracts
this logic away in a safer way.

* Changelog: reorder entries chronologically based on PR ID
`_` as prefix is intended for unused variables and bindings; it should
be used in suffix position when intending to prevent a clash with a
keyword instead.
* Omit wrapper functions on Fp structs
These wrappers contributed thousands of lines of code but offered
insignificant ergonomic benefit as the same functions are also wrapped
at a higher level and, if necessary, wrapper functions can be called
directly.
* Standardize on direct fp table access in wrapper functions
* Constify generated extension names
* Constify hand-written extension names
* Make ash-window list extensions as &[*const c_char]
This alters enumerate_required_extensions() to return the same type that
is expected by vk::InstanceCreateInfoBuilder::enabled_extension_names(),
allowing simple Vulkan apps to omit the boilerplate of mapping to an
intermediate Vec<*const c_char>.

While making the code only marginally harder to read such casts can also
introduce subtle bugs when used incorrectly, and are best omitted
whenever unnecessary: Rust already coerces borrows into raw pointers
when the types on both ends are clear, and even then there remain many
casts that are identical to the source type.
In addition these errors show up when using a local crate reference to
`ash` in a workspace that uses "the `.cargo/config.toml` setup" from
[EmbarkStudios/rust-ecosystem#68] to configure linter warnings
project-wide instead of for all crates in that workspace individually.
In our case aforementioned linter warnings are enabled on top of
Embark's configuration, leading to a lot of these warnings in our build
process.

Much like `platform_types.rs` and `vk.rs` before, there is no need to
generate this file as its contents are completely static. This allows
direct editing of the file without realizing that a copy lives in the
generator - and will overwrite `macros.rs` when the generator is being
run.
This name is emitted by the generator and already known to not contain
any null-characters: replace the runtime iteration+comparison (hidden
behind `from_bytes_with_nul`) and `.expect()` panic with an `unsafe`
"cast" through `from_bytes_with_nul_unchecked`, just like the
function-pointer loaders.
Instead of generating an impl block - together with "Generated from XXX"
doc - for every single item that extends an enum type, group all these
extensions together in a single `impl` block per extension per type.
This cuts down a couple thousand lines of repeated `impl T` and `#[doc]`
annotations, and makes the code more readable at the same time: it is
now possible to immediately see exactly all the constants that a certain
extension extends a type with.
Back when we were still trying to come up with sensible names for
"deprecated" aliases (initially introduced as self-supporting constants)
that don't adhere to the naming standard but only remain to exist for
backwards compatibility, some of these aliases would get the same name
as the enum constant they were aliasing, resulting in (compile-time)
conflicts.
Now that all those aliases are simply not generated anymore (end-users
should just pick the properly named variant) it is not necessary to
check for and prevent these conflicts on the generator side anymore.
`constants` is iterated twice here: once with a filter, the other time
without, and the results are zipped together. Besides being able to
simplify the entire execution to just one `iter()` without intermediary
iterators, removing `.zip()` makes it impossible for the results in both
iterators to get mismatched when the `filter` inevitably skips elements.
Fortunately no such cases seem to exist, or at least not that effect the
resulting generated code.
Some clippy lint long ago apparently suggested to explicitly specify a
type for all random generators in 8550683 ("Address all the clippy lints
(#233)"), so the `impl BuildHasher` trait was apparently passed as a
placeholder for the `RandomState` default that's selected.
This does not serve any purpose and that (likely bogus) clippy warning
no longer shows up, making it safe to remove the trait.
vk.xml now contains the comment text "Backwards-compatible alias
containing a typo" which we can use to detect intentional renames,
without needing to specify explicit overrides/exceptions in the
generator anymore.
These deprecated constants exist for the sole reason of backwards
compatibility which Vulkan cannot permit itself to remove in the C
headers, but are unreasonable for crate authors to use anyway due to
their `#[deprecated]` annotation whose cargo-check warnings are easy to
fix by just using the non-deprecated variant instead. Furthermore, Ash
is still allowing itself to perform breaking changes in its releases
making this the perfect time to get rid of all these useless variants
and the generator support code that comes with it. No need to come up
with a "more proper" variant name if we don't generate those that
"intentionally" fail to adhere to the "enum variant name" specification
in the first place.
The `all()` function only represents bitflags known in the core of
Vulkan; it omits all bits added by extensions making this function
unrepresentative and has hence been scheduled for removal for quite some
time to get rid of the confusion it causes.
Alternatively the generator could be taught to collect bitflags added by
extensions, but new extensions get added over time skewing available
values in ash versus the current driver/environment. This makes the
value from `all()` unreliable and fragile at best.
`-` and `-=` (`sub()` and `sub_assign()`) are also controversial by
nature since the underlying value represents an integer but the
implemented math uses bitwise operators. This is a confusing design
pattern and the caller better replaces their uses - if any at all - with
`foo &= !BAR`.

* Update Vulkan-Headers to 1.2.195
Includes the new VK_EXT_rgba10x6_formats, VK_KHR_format_feature_flags2
and VK_KHR_maintenance4 extensions.
* Update Vulkan-Headers to 1.2.196
Includes Vulkan-Headers fixup commit with the missing h265 encode

* generator: Use `Self` instead of `$name` in macros
Saves a bit of unnecessary expansion inside the macro.
* Fix remaining violations of clippy::use_self in generated code
* generator: Remove unnecessary match on reference type
* ash: Exclude static `vk.rs` from the generator
Much like `platform_types.rs` `vk.rs` does not contain any generated
code that depends on `Vulkan-Headers`' `vk.xml`, making it easier to
just keep this file manually editable.
* Add Packed24_8 helper-type for constructing AS Instance bitfields
* Update Vulkan-Headers to 1.2.187; drop Video enum-variant edgecases
* Update Vulkan-Headers to 1.2.188
* generator: Improve support for pointers to static-sized arrays
Vulkan 1.2.188 removed the only occurence of `ename:`, which was our
heuristic to find a type that's a pointer to a static-sized array. It
is now replaced with a "normal" `latexmath:` expression, but should
still be dealt with appropriately.
Note that all `latexmath:` conditions have been removed, as these fields
should not be silently omitted. As of this Vulkan version only 3 exist,
and all have their own edge-case.
* Revert "Remove upstream-fixed vk_platform.h header path fallback"
This reverts commit 43dee26ec04dfd3871da8a11b624eaf9fbd16f3a.
Upstream is reverting back to inconsistent paths in [this commit] to
counter unintentional header `#include` changes on the C-side:
https://github.com/KhronosGroup/Vulkan-Docs/issues/1573
[this commit]: 8bde11cbd7
* generator: Remove unnecessary `-Iinclude/vulkan` directory
Every `#include` path (except `"vk_platform.h"`, see previous commit) is
relative to the `include/` directory or the current file, and does not
look for a path relative to `include/vulkan/`.
* Update Vulkan-Headers to 1.2.189
* Update Vulkan-Headers to 1.2.190
* Update Vulkan-Headers to 1.2.191
* Update Vulkan-Headers to 1.2.176
* Update Vulkan-Headers to 1.2.177
* Update Vulkan-Headers to 1.2.178
This requires `len="null-terminated"` to be added to
`VkCuFunctionCreateInfoNVX::pName` in `vk.xml`.
* Update Vulkan-Headers to 1.2.179
* Update Vulkan-Headers to 1.2.181
Skipping 1.2.180 due to missing VkPipelineLayoutCreateFlagBits, which is
defined now.
* push_next and Extends traits are generated for all root structs.
root structs are now all structs that are extended by other structs!
root structs used to be all structs that don't extend any other structs.
* the root_structs local variable that is passed around is now a set of Ident (and no String).
