chore: disable hermes via gradle project env var (#18675)

fixes #18493

We enabled `hermes` for android in the `react-native` upgrade to `0.72.5`
Although things seemed fine but developers were seeing frequent crashes in their local environment.

After some investigation the crashes were traced to max native call stack depth in `hermes` engine.
Disabling `hermes` for local debug builds helps fix that issue.

This commit disables `hermes` by default with the help of a exporting an environment variable in the `make run-android` command.
It is annoying that this also modifies `android/gradle.properties` so we keep `hermesEnabled` as `false` there as well.
We also enable `hermes` when generating release builds so that we can take advantage of `hermes` engine in release builds.

We also add a log to print whether `hermes` is enabled or not. I think its helpful to have this so that we know whether `hermes` is enabled or not.
