fixes#19081
## Summary
This PR aims to improve android build step for debug variants by ensuring we do not rebuild the android derivation for any change made to `clojurescript` code.
We also do the following things :
- enable `JVM` parallel garbage collector.
- get rid of `dexOptions` which was deprecated in `gradle 8`.
- add additional `parallel` flag to `gradle` to speed up builds.
## Review notes
- `make run-clojure`
- `make run-android`
- ctrl + C on android terminal and edit any `cljs` file
- `make run-android` ( should build almost instantly )
fixes#18831
We update the nix derivation to build android by passing `hermesEnabled` flag which checks the environment variable and if the environment variable is not set we default `hermesEnabled` to `true`.
This ensures that `hermes` is disabled for debug builds and enabled for release builds.
In this commit we also
- rename `nix/mobile/android/release.nix` → `nix/mobile/android/build.nix` since that nix file no longer generates release only builds.
- cleanup 2 other env vars and use the `gradle` project format
- replace `BUILD_NUMBER` with `verisonCode` for consistency
- replace `androidGradleOpts ` with `buildUrl `
- bump `status-jenkins-lib` to v1.8.7
