He Junyan d72f818029 libs: utils: h265: Use get_profile_from_sps to get profile.
We now use gst_h265_get_profile_from_sps() to replace the old way
of gst_h265_profile_tier_level_get_profile() to get more precise
profile. The new function consider the unstandard cases and give
a more suitable profile decision.
