Windows: Implement EventLoopExtPumpEvents and EventLoopExtRunOnDemand 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`.
