Add comments and basic reformatting for new files.

Ic4df2a9a introduced new keyboard layouts for Hebrew and Arabic.
This change adds a comment to them alongside with trailing
whitespace suppression.

This change explicitly limits its scope to files introduced by
Ic4df2a9a. It replaces I48927626 which has been deemed too reckless.
