Up until now the Android backend has been directly mapping key codes
which essentially just represent the "physical" cap of the key (quoted
since this also related to virtual keyboards).
Since we didn't account for any meta keys either it meant the backend
only supported a 1:1 mapping from key codes, which only covers a tiny
subset of characters. For example you couldn't type a colon since
there's no keycode for that and we didn't try and map Shift+Semicolon
into a colon character.
This has been tricky to support because the `NativeActivity` class doesn't
have direct access to the Java `KeyEvent` object which exposes a more
convenient `getUnicodeChar` API.
It is now possible to query a `KeyCharcterMap` for the device associated
with a `KeyEvent` via the `AndroidApp::device_key_character_map` API
which provides a binding to the SDK `KeyCharacterMap` API in Java:
https://developer.android.com/reference/android/view/KeyCharacterMap
This is effectively what `getUnicodeChar` is implemented based on and is
a bit more general purpose.
`KeyCharacterMap` lets us map a key_code + meta_state from a `KeyEvent`
into either a unicode character or dead key accent that can be combined
with the following key. This mapping is done based on the user's chosen
layout for the keyboard.
To enable support for key character maps the
`AndroidApp::input_events()` API was replaced by
`AndroidApp::input_events_iter()` which returns a (lending) iterator for
events. This was changed because the previous design made it difficult
to allow other AndroidApp APIs to be used while iterating events (mainly
because AndroidApp held a lock over the backend during iteration)
Unfortunately this isn't a total removal, for two reasons:
- We still need "libc" for the Xlib XIM implementation, for locales.
- BSD requires libc to check for main-threadedness.
First one we can likely resolve in the near future, not so sure about
the second one without using some weird pthreads trick.
The utils in this module should help the users to activate the windows
they create, as well as manage activation tokens environment variables.
The API is essential for Wayland in the first place, since some
compositors may decide initial focus of the window based on whether
the activation token was during the window creation.

Overhaul the keyboard API in winit to mimic the W3C specification
to achieve better crossplatform parity. The `KeyboardInput` event
is now uses `KeyEvent` which consists of:
- `physical_key` - a cross platform way to refer to scancodes;
- `logical_key` - keysym value, which shows your key respecting the
layout;
- `text` - the text produced by this keypress;
- `location` - the location of the key on the keyboard;
- `repeat` - whether the key was produced by the repeat.
And also a `platform_specific` field which encapsulates extra
information on desktop platforms, like key without modifiers
and text with all modifiers.
The `Modifiers` were also slightly reworked as in, the information
whether the left or right modifier is pressed is now also exposed
on platforms where it could be queried reliably. The support was
also added for the web and orbital platforms finishing the API
change.
This change made the `OptionAsAlt` API on macOS redundant thus it
was removed all together.

This update rewrites the winit's Wayland backend using new wayland-rs
0.30 API. This fixes long standing issue with the forward compatibility
of the wayland backend, meaning that future updates to the wayland
protocol won't break rust code anymore. like it was before when adding
new shm/enum variants into the protocol.
