win: avoid ID mixups on refresh (#12869)

Browse source 
On Windows AMD IDs are numeric, and can reorder based on the filter environment.
By passing in the filter env on a full discovery refresh, we'll only look at the actual devices
and ignore unsupported iGPUs.  Without this, on some systems iGPU VRAM was incorrectly
being used to populate the dGPU.
