android-activity/examples/agdk-winit-wgpu

This tests using GameActivity with winit and wgpu.

This is based on a re-worked winit backend here: https://github.com/rib/winit/tree/android-activity

Although it would have been possible to handle the suspend/resume lifecycle events with a simpler approach of destroying and recreating all graphics state, this tries to represent how lifecycle events could be handled in more complex applications, such as within Bevy.

Considering that lifecycle events aren't supported consistently on desktop platforms this test also aims to build and run on desktop - for the sake of testing how more complex applications (that need to be portable) can work. (enable "desktop" feature to build binary)
