Ban op->idc that may drop all layer-specific OBUs
If c->operating_point_idc is nonzero and either bits 0-7 or bits 8-11 in it are all 0s, it will cause dav1d_parse_obus() to drop all layer-specific OBUs. Prohibit any op->idc with such properties because it could be selected as c->operating_point_idc.
