Deprecate window creation with stale event loop

Browse source 
Creating window when event loop is not running generally doesn't work,
since a bunch of events and sync OS requests can't be processed. This
is also an issue on e.g. Android, since window can't be created outside
event loop easily.

Thus deprecate the window creation when event loop is not running,
as well as other resource creation to running event loop.

Given that all the examples use the bad pattern of creating the window
when event loop is not running and also most example existence is
questionable, since they show single thing and the majority of their
code is window/event loop initialization, they wore merged into
a single example 'window.rs' example that showcases very simple
application using winit.

Fixes #3399.

- On X11, fix xkb state not being updated correctly sometimes leading to wrong input.
- Fix compatibility with 32-bit platforms without 64-bit atomics.
- Implement `Sync` for `EventLoopProxy<T: Send>`.
- **Breaking:** Move `Window::new` to `ActiveEventLoop::create_window` and `EventLoop::create_window` (with the latter being deprecated).
- **Breaking:** Rename `EventLoopWindowTarget` to `ActiveEventLoop`.
- **Breaking:** Remove `Deref` implementation for `EventLoop` that gave `EventLoopWindowTarget`.
- **Breaking**: Remove `WindowBuilder` in favor of `WindowAttributes`.
- On X11, fix swapped instance and general class names.
- **Breaking:** Removed unnecessary generic parameter `T` from `EventLoopWindowTarget`.
- On Windows, macOS, X11, Wayland and Web, implement setting images as cursors. See the `custom_cursors.rs` example.
@ -47,7 +51,7 @@ Unreleased` header.
- Added `EventLoop::builder`, which is intended to replace the (now deprecated) `EventLoopBuilder::new`.
- **Breaking:** Changed the signature of `EventLoop::with_user_event` to return a builder.
- **Breaking:** Removed `EventLoopBuilder::with_user_event`, the functionality is now available in `EventLoop::with_user_event`.
- Add `Window::builder`, which is intended to replace the (now deprecated) `WindowBuilder::new`.
- Add `Window::default_attributes` to get default `WindowAttributes`.
- On X11, reload dpi on `_XSETTINGS_SETTINGS` update.
- On X11, fix deadlock when adjusting DPI and resizing at the same time.
- On Wayland, fix `Focused(false)` being send when other seats still have window focused.

When using so called 'natural scrolling' (scrolling that acts like on a touch screen), this is what to expect:
Moving your finger downwards on a scroll wheel should make the window move down, and you should see a positive Y scroll value.
When moving fingers on a trackpad down and to the right, you should see positive X and Y deltas, and the window should move down and to the right.
With reverse scrolling, you should see the inverse behavior.
In both cases the example window should move like the content of a scroll area in any other application.
In other words, the deltas indicate the direction in which to move the content (in this case the window)."

This example draws a circle in the middle of a 4/1 aspect ratio canvas which acts as a useful demonstration of winit's resize handling on web.
Even when the browser window is resized or aspect-ratio of the canvas changed the circle should always:
* Fill the entire width or height of the canvas (whichever is smaller) without exceeding it.
* Be perfectly round
* Not be blurry or pixelated (there is no antialiasing so you may still see jagged edges depending on the DPI of your monitor)
Currently winit does not handle resizes on web so the circle is rendered incorrectly.
This example demonstrates the desired future functionality which will possibly be provided by https://github.com/rust-windowing/winit/pull/2074
