Update presubmit mapping for MediaProjection & related

The desired end state:
1) run unit tests when anything in `android.media.projection` changes
2) TODO - tracked by b/265302522 - run CTS tests when anything in `android.media.projection` changes

Tested with "test-mapping" command; runs all presubmit tests in the given directory and parent folders.

Bug: 245745197
Test: atest --test-mapping media/java/android/media/projection:presubmit
