Instead of initialize the chroma_type with a undefined value, which will be converted to GST_VAAPI_CHROMA_TYPE_YUV420 by GstVaapiContext, this patch queries the VA config, given the received GstVaapiContextInfo's parameters, and gets the first response. In order to get the GstVaapiChromaType value, also it was needed to add a new utility function: to_GstVaapiChromaType(), which, given a VA_RT_FORMAT_* will return the associated GstVaapiChromaType. https://bugzilla.gnome.org/show_bug.cgi?id=771291
