Import android-games-sdk changes for 4.0.0

This imports the SDK from commit 090732c3ca7d8b47ed39e028081d685e4097db7f, from:
https://github.com/rust-mobile/android-games-sdk/commits/android-activity-4.0.0

This imports a patch to revert the recent addition of a
`_rust_glue_on_create_hook` in favour of fixing the Rust wrapper for
`GameActivity_onCreate` which is more consistent with the
`ANativeActivity_onCreate` entrypoint that we have in the `native-activity`
backend.

This also:
- Fixes a related rerun-if-changed path in build.rs
- Removes the reference to _rust_glue_on_create_hook src/game_activity/mod.rs
