plugins: create a proxy for GstVaapiUploader allocated buffers.

Browse source 
Always make sure to allocate a VA surface proxy for GstVaapiUploader
allocated buffers, i.e. make gst_vaapi_uploader_get_buffer() allocate
a proxy surface.

This fixes cases where we want to retain the underlying surface longer,
instead of releasing it back to the surface pool right away.
