Add support for the GuC uncorrectable local error G2H notification and
opt in to the feature when the submission ABI exposes it.
Preserve HW error state in wedged mode 2 to help debug the root cause of
the error.

---
History:
v4: Add wedged mode==2 handling patch
v3: Remove not used flag bit and timeout worker check (Daniele)
    Remove wedged mode==2 check, which will be handled in separate patch(Daniele)
v2: Opt in for Xe3p only, excluding media GTs on NovaLake-P which don't support the feature
    Remove timeout bypass, which is outside the scope of this patch and can be added separately
