Eliminate usage of OBJ_FREEZE_RAW

Previously it would bypass the `FL_ABLE` check, but
since shapes introduction, it started having a different
behavior than `OBJ_FREEZE`, as it would onyl set the `FL_FREEZE`
flag, but not update the shape.

I have no indication of this causing a bug yet, but it seems
like a trap waiting to happen.
