backends/native: Move primary_gpu into MetaRendererNative

Browse Source 
Make the choosing and identity of the primary GPU an internal detail to
the native renderer. MonitorManagerKms did not need it for anything.

The primary GPU logic remains unchanged.

This allows follow-up patches to change how the renderer chooses the
primary GPU. It will be easier for the renderer to use private
information for choosing.
