gstvaapisurfacepool: Add new API to create surface pool based on chroma type

Browse source 
This new API gst_vaapi_surface_pool_new_with_chroma_type() is for
creating a new GstVaapiVideoPool of GstVaapiSurfaces with the specified
chroam type and dimensions. The underlying format of the surfaces is
implementation (driver) defined.
