If the input video format is VUYA, the main-444 profile should be auto choosed. We modify to let get_allowed_profiles of each encode sub class to return an array of all supported profiles based on downstream's allowed caps, or return NULL if no valid profiles specified by downstream. If no allowed profiles found, all profiles which belong to the current encoder's codec will be the candidates. The function gst_vaapi_encoder_get_surface_attributes collects the surface's attributes for that profile list we just get. So for this case, both NV12 and VUYA should be returned.
