Updates all the things

For each example, this:
- Updates to using Android Gradle Plugin 8.0
- Adds ndkVersion to build.gradle
- Updates all cargo deps and fixes / updates examples as needed
- Avoids depending on any git branches for winit/egui now that the
  required Android support is upstream.
- Removes all .idea files and adds .idea to .gitignore

Adds a na-egui example that tests NativeActivity + Egui
(same code as agdk-egui, but built against NativeActivity instead of
GameActivity)

This updates .github/workflows/ci.yml so all examples are built
and `./gradlew build` is run - not just `cargo ndk build`
