Fix default CPB buffer size to something more reasonable (1500 ms)
and that still fits the level limits. This is a non configurable
property for now. The initial CPB removal delay is also fixed to
750 ms.

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
