Revert "On Wayland, fix resize not propagating properly"

This reverts commit 78e5a395da.

It was discovered that in some cases mesa will lock the back
buffer, e.g. when making context current, leading to resize
missing. Given that applications can restructure their rendering
to account for that, and that winit isn't limited to playing
nice with mesa reverting the original commit.

 - **Breaking:** Replaced `EventLoopExtUnix` with `EventLoopBuilderExtUnix` (which also has renamed methods).
 - **Breaking:** The platform specific extensions for Windows `winit::platform::windows` have changed. All `HANDLE`-like types e.g. `HWND` and `HMENU` were converted from winapi types or `*mut c_void` to `isize`. This was done to be consistent with the type definitions in windows-sys and to not expose internal dependencies.
 - The internal bindings to the [Windows API](https://docs.microsoft.com/en-us/windows/) were changed from the unofficial [winapi](https://github.com/retep998/winapi-rs) bindings to the official Microsoft [windows-sys](https://github.com/microsoft/windows-rs) bindings.
-- On Wayland, fix resize and scale factor changes not being propagated properly.
 - On Wayland, fix polling during consecutive `EventLoop::run_return` invocations.
 - On Windows, fix race issue creating fullscreen windows with `WindowBuilder::with_fullscreen`
 - On Android, `virtual_keycode` for `KeyboardInput` events is now filled in where a suitable match is found.
