radeonsi: add AMD_DEBUG=extra_md

Browse source 
When this debug flag is set, the driver sets the umd metadata for
all color textures and enables the use of extended metadata.

Extended metadata allows umr to import textures and setting these
on all color texture allows to import non-exported textures
(eg: dGPU draw surface when DRI_PRIME=1 is used).
