libs: encoder: initialize chroma_type

Browse source 
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.
