h264parse: Align GST_H264_PROFILE_HIGH_422 to H264 standards

Stéphane Cerveau requested to merge dabrain34/gst-plugins-bad:dab_h264parse_add_profile into master

According to H264 ITU standards from 06/19, GST_H264_PROFILE_HIGH_422 (profile_idc = 122) with constraint_set1_flag = 0 and constraint_set3_flag = 0 can be mapped to high-4:2:2 or high-4:4:4. GST_H264_PROFILE_HIGH_422 with constraint_set1_flag = 0 and constraint_set3_flag = 1 can be mapped to high-4:2:2, high-4:4:4, high-4:2:2-intra or high-4:4:4-intra.
