Silence unnecessary Gradle outputs - Part 1 (#46704)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46704

Our build log for Gradle is extremely noisy due to Hermes.
Here I'm suppressing all the build output from Hermes as we can't really do much from that side of the build.

This should make it easier for folks on GitHub Actions to immediately spot where are failures.
