utils: add new H.264 helper functions.
* 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
