* generator: Add edegecases for broken Video extension enum variants
* Replace deprecated `make_version()` with `make_api_version()`
* generator: Use the same predicate for push_next and its traits
Some structs turn out to be root structs when their name is not in the
`root_structs` set, even when they themselves extend another struct.
This was already taken care of for `push_next` which is emitted in this
situation, but the trait referenced by `push_next`'s `T` bound is still
relying on the `extends` field to not exist in `vk.xml` at all, leading
to it not being generated despite `push_next` needing it.
Fixes: 215511f ("Implement ExtendXXX for multiple root create infos if
there are more than 1")
* Update Vulkan-Headers to 12.175
* generator: Generate low-level structs with bindgen (for vk_video)
* Add ash-window as workspace member
* ash-window: fix repository link
* ash-window: Address CI fmt&clippy issues
* ash-window: Try fix SDL2 CI issues
