drm-shim: Add primary node support
What does this MR do and why?
drm-shim: Add primary node support
Currently only the more commonly used render node is listed on the fake /dev/dri directoy and returns a valid file descriptor. This mirrors that functionality over to the primary node so applications that assert for it can run under the drm-shim with no modifications, as the primary node is expected to always exist.
Closes: #9924
