There seems to be many PRs relating to this issue, but they don't include all
platforms and for some reason lost steam. This PR again tries to make this
feature happen, and does it for all desktop platforms (x11, wayland, macos,
windows, web).
I think the best user of this feature and the reason I'm doing this is Bevy and
game engines in general. There non laggy hardware cursors with custom images are
very important. Game devs also like their PNGs so supporting platform native
cursor files is not that important, but I guess could be added too.

When calling `Window::request_redraw` from the `RedrawRequested`
handler the `RedrawWindow` won't result in `WM_PAINT` being delivered
due since user callback is run before `DefWindowProcW` is called.
Track whether the user called `Window::request_redraw` and ask for
`RedrawWindow` after running the said function during `WM_PAINT`
handling.
Fixes#3150.
Window builder is always accessed by winit on the thread event loop
is on, thus it's safe to mark the data it gets as `Send + Sync`.
Each unsafe object is marked individually as `Send + Sync` instead
of just implementing `Send` and `Sync` for the whole builder.
Fixing this could require a massive rework to how redraw is handled
on windows to the point of removing `WM_PAINT`, since it's not reliable
by any means for our use case.
For now at least document that the API is broken. It was broken like
that for a long while.
Add a method to request a system menu. The implementation
is provided only on Windows for now.

* Make Linux platforms less dependent on the root monitor handle
* Add various functions to the Wayland platform to reduce cfgs
* Don't use a cfg in listen_device_events
* Don't use a cfg in set_content_protected
* Fix instance of a target_os cfg
We use raw-window-handle extensive in the public API as well as we
force the users to use it to get some essential data for interop, thus
reexport it.
Fixes: #2913.
Inner panics could make it hard to trouble shoot the issues and for some
users it's not desirable.
The inner panics were left only when they are used to `assert!` during
development.
This reverts commit 9f91bc413fe20618bd7090829832bb074aab15c3 which
reverted the original patch which was merged without a proper review.
Fixes: #500.

A surprising amount of work was required to enable these extensions
on Windows.
I had originally assumed that pump_events was going to be very similar
to run except would use PeekMessageW instead of GetMessageW to avoid
blocking the external loop but I found the Windows backend broke
several assumptions I had.
Overall I think these changes can hopefully be considered a quite a
significant simplification (I think it's a net deletion of a fair amount
of code) and I think it also helps bring it into slightly closer alignment
with other backends too
Key changes:
- I have removed the `wait_thread` that was a fairly fiddly way of handling
`ControlFlow::WaitUntil` timeouts in favor of using `SetTimer` which works
with the same messages picked up by `GetMessage` and `PeekMessage`.
- I have removed the ordering guarantees between `MainEventsCleared`,
`RedrawRequested` and `RedrawEventsCleared` events due to the complexity in
maintaining this artificial ordering, which is already not supported
consistently across backends anyway (in particular this ordering already
isn't compatible with how MacOS / iOS work).
- `RedrawRequested` events are now directly dispatched via `WM_PAINT` messages
- comparable to how `RedrawRequested` is dispatched via `drawRect` in the
MacOS backend.
- I have re-worked how `NewEvents`, `MainEventsCleared`, and `RedrawEventsCleared`
get dispatched to be more in line with the MacOS backend and also more in line
with how we have recently discussed defining them for all platforms.
`NewEvents` is conceptually delivered when the event loop "wakes up" and
`MainEventsCleared` gets dispatched when the event loop is about to ask the
OS to wait for new events.
This is a more portable model, and is already how these events work in the
MacOS backend.
`RedrawEventsCleared` are just delivered after `MainEventsCleared` but this
event no longer has a useful meaning.
Probably the most controversial thing here is that this "breaks" the ordering
rules for redraw event handling, but since my changes interacted with how the
order is maintained I was very reluctant to figure out how to continue
maintaining something that we have recently been discussing changing:
https://github.com/rust-windowing/winit/issues/2640.
Additionally, since the MacOS backend already doesn't strictly maintain this
order it's somewhat academic to see this as a breakage if Winit applications
can't really rely on it already.
This updates the documentation for `request_redraw()` to reflect that we
no longer guarantee that `RedrawRequested` events must be dispatched
after `MainEventsCleared`.
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.
Fixes#2279.
