ibaker d76ee54ca6 Add two MP4 samples with metadata
The first has a string genre, and various other values set, generated
from `sample.mp4` with the command below [1].

The second has a numeric genre, to test `gnre` atom parsing. This
parsing is currently broken, the fix is in a follow-up change. This
file was also generated from `sample.mp4` with the command below [2].

This change also includes `CommentFrame.text` in its `toString`
representation, otherwise there's no difference between e.g. different
levels of `ITUNESADVISORY` in the extractor dump files.

Issue: androidx/media#1305
