f68e579044 docs/panfrost: Document drm-shim usage 
Document how to build and use Panfrost's drm-shim implementation. I hope by
documenting this process, other Mesa developers are better able to test
Panfrost. In particular, this allows developers without Mali hardware to run
shader-db for any Mali target, which may be useful for debugging regressions
from common NIR changes.

drm-shim is not a substitute for testing against real hardware.

Special thanks to Emma Anholt and Icecream95 for building this infrastructure.

This documentation is linked bidirectionally with both implementations, so it
