Handle READ_MEDIA_IMAGES/VIDEO permission in getPermissionRequestState API

READ_MEDIA_IMAGES permission becomes USER_FIXED, if user allows
only selected photos twice in permission dialog.
USER_FIXED flag is generally treated as permanent denial from user,
and subsequent permission request will be ignored by the system.

But due to photo picker, we treat READ_MEDIA_IMAGES a bit
differently. The system doesn't ignore permission request
even after USER_FIXED flag in this case, rather the
system shows photo picker directly.

Adding this special case to handle READ_MEDIA_IMAGES in new
getPermissionRequestState API, when determining whether a
permission can be requested or not.
