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 )
