media: Rename PERMISSION_PROTECTED_MEDIA to PERMISSION_PROTECTED_MEDIA_IDENTIFIER.

media: Rename PERMISSION_PROTECTED_MEDIA to PERMISSION_PROTECTED_MEDIA_IDENTIFIER.

This makes the naming consistent with other use cases, e.g. CONTENT_SETTINGS_TYPE_PROTECTED_MEDIA_IDENTIFIER, ProtectedMediaIdentifierPermissionContext etc.

TEST=Renaming only.
