drm/amdgpu: update ras capability's query based on mem ecc configuration
RAS support capability needs to be updated on top of different
memeory ECC enablement, and remove redundant memory ecc check
in gmc module for vega20 and arcturus.
v2: check HBM ECC enablement and set ras mask accordingly.
v3: avoid to invoke atomfirmware interface to query twice.
