[GL] Testing with the Android Emulator on CI

[Gordon-F]

Just a proof-of-concept of how we can run a quad example on CI with the Android Emulator.

All other jobs temporary removed (for speed up).

TODO:

• [ ] Rollback all CI jobs
• [ ] Investigate why half of builds panicked with error: thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', /Users/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/ndk-glue-0.2.1/src/lib.rs:255:34 https://github.com/rust-windowing/android-ndk-rs/issues/116
• [ ] Investigate how we can run quad on Android without code duplication
• [ ] Add PR comments with results screenshot and logs

I'm going to close this PR, since gfx-hal is deprecated. I will try to run this PR on top of wgpu or wgpu-hal when I had more free time.
