Allow user to precise the largest profile to use for encoding due
to target decoder constraints. For instance, if CABAC entropy coding
mode is requested by "constrained-baseline" profile only is desired,
then an error is returned during codec configuration.
Also make sure that the suitable profile we derived actually matches
what the HW can cope with.

Instal <gst/vaapi/gstvaapiutils_h264.h> header but only expose the
H.264 levels in there. The additional helper functions are meant
to be private for now.
- gst_vaapi_utils_h264_get_level():
Returns GstVaapiLevelH264 from H.264 level_idc value
- gst_vaapi_utils_h264_get_level_idc():
Returns H.264 level_idc value from GstVaapiLevelH264
- gst_vaapi_utils_h264_get_level_limits():
Returns level limits as specified in Table A-1 of the H.264 standard
- gst_vaapi_utils_h264_get_level_limits_table():
Returns the Table A-1 specification
* Profiles:
- gst_vaapi_utils_h264_get_profile():
Returns GstVaapiProfile from H.264 profile_idc value
- gst_vaapi_utils_h264_get_profile_idc():
Returns H.264 profile_idc value from GstVaapiProfile
* Chroma formats:
- gst_vaapi_utils_h264_get_chroma_type():
Returns GstVaapiChromaType from H.264 chroma_format_idc value
- gst_vaapi_utils_h264_get_chroma_format_idc():
Returns H.264 chroma_format_idc value from GstVaapiChromaType
