va: Attempt to load driver name as path as fallback

sivileri · sivileri · commit afda003355af · 2023-06-09T12:06:00.000-04:00
This fixes loading of the registry driver full path for a given adapter/device by LUID.
This now allows LIBVA_DRIVER_NAME pointing to a path (any LoadLibrary allowed path string)

No changes to existing loading mechanisms, which will still work the same, just extending new functionality when the existing ones fail.
