Not using `NSColor::clearColor()` results in Quartz thinking that the
window is not transparent at all, which results in artifacts.
However, not setting the `windowBackgroundColor` in
`Window::set_transparent` results in border not properly rendered.

I'm preparing to get rid of our application delegate in favour of registering
notification observers, to do so I'm renaming `app_delegate.rs` to
`app_state.rs`, and moving the functionality out of the Objective-C method
into a normal method.
Additionally, `AppState` previously implemented `Default`, but really, this
was a hack done because someone (probably myself) was too lazy to write out
the full initialization in `AppDelegate::new`.
* Use AppKit's internal queuing mechanisms
This allows events to be queued in a more consistent order, they're now
interleaved with events that we handle immediately (like redraw events),
instead of being handled afterwards.
* Only queue events if necessary
This makes the call stack / backtraces easier to understand whenever
possible, and generally improves upon the order in which events are
delivered.
This fixes an issue where the window glitched due to resize
when the user doesn't actually change the window, but macOS
function to update window size was still called.
On Raspberry Pi, using the Rust crate eframe caused the program to crash on
mouse movement. The Backtrace lead to this specific line of code, and the exact
error was a "misaligned pointer dereference: address must be a multiple of 0x8
but is xxxx"
The edit has been tested with the Raspberry Pi, which works now.
- Allow all gestures simultaneously recognized.
- Add PanGestureRecogniser with min/max number of touches.
- Fix sending delta values relative to Update instead to match macOS.
- Fix rotation gesture units from iOS to be in degrees instead of radians.

Setting the background color changes how the window title bar appears,
which is something that the application should customize itself if it
wants this behaviour (and also, it wasn't set when calling
`set_transparent`, so the behaviour wasn't consistent).
On Windows, it is generally unsafe to use the HWND outside of the thread
that it originates from. In reality, the HWND is an index into a
thread-local table, so using it outside of the GUI thread can result in
another window being used instead, following by code unsoundness. This
is why the WindowHandle type is !Send. However, Window is Send and Sync,
which means we have to account for this.
Thus far the best solution seems to be to check if we are not in the GUI
thread. If we aren't, refuse the return the window handle.
For users who want to ensure the safety themselves, the unsafe API
was added.

This replaces a reference to EventLoopBuilderExtUnix in a panic

In rare cases destroying subsurfaces before the main surface could
result in a frame where the window is still shown, but decorations
got hidden, right before the window itself disappears.
Changes relevant to Winit:
- `icrate` has been deprecated in favour of separate crates per
framework, in our case `objc2-foundation` and `objc2-app-kit` (and in
the future `objc2-ui-kit` on iOS).
- Moved `MainThreadMarker::run_on_main` to free-standing function
`run_on_main`.
- Changed how features work, this should result in less code that we
need to compile.
- Enums are now real structs instead of type-aliases and free constants.
There are AV rules out there which cause almost any
program that contains github URLs to become marked as malware.
While those rules are spurious, they're years old, and AV vendors have a
very poor reputation at appropriately following up with these problems.
Remove these strings from the panic data present in the binary
prevents binaries linking the winit from being spuriously marked as
Trojan:Win32/Wacatac.B!ml.
In particular, we don't want to emit those events inside of
`pressureChangeWithEvent:`, since the mouse motion value is sometimes
outdated.
Additionally, we want to ensure the events have been emitted during
other gestures.

This fixes issues where a hidden and grabbed cursor could leave the
window and become visible on top of the windows taskbar (and potentially
leave the window altogether if the taskbar is clicked) under at least
two occasions:
- When a window is overlapping the taskbar.
- When a window is maximized and Automatically hide the taskbar has
been enabled.
This approach of confining the cursor to the center of the window is
used in SDL.
Add a simple `ApplicationHandler` trait since winit is moving towards
trait based API. Add `run_app` group of APIs to accept `&mut impl
ApplicationHandler` deprecating the old `run` APIs.

Invert the mouse delta filter, so it aligns with the intention of

Usually, if mouse events are equal to (0, 0) we filter them out.
However, if the event is very close to zero it will still be given to
the user. In some cases this can be caused by bad float math on the X11
server side.
Fix it by filtering absolute values smaller than floating point epsilon.

Closes: #3500
* Convert usage of Lazy to OnceLock on macOS and iOS
* Remove a few uses of Lazy that wrapped Mutex or RwLock
The `new` functions on these were made `const` in Rust 1.63.0
* Use AtomicBool instead of RwLock
This makes our use of `unsafe` to make the event handler temporarily 'static be local to a module, in a way that's (hopefully) much easier to reason about.
