Fix lookup for a suitable HW profile, as to be used by the underlying hardware, based on heuristics that lead to characterize the SW profile, i.e. the one used by the SW level encoding logic. Also fix constraint_set0_flag (A.2.1) and constraint_set1_flag (A.2.2) as they should respectively match the baseline and main profile. https://bugzilla.gnome.org/show_bug.cgi?id=719827
