drm/xe/guc: Port Wa_22012727170/Wa_22012727685 to xe_wa

Wa_22012727170 and Wa_22012727685 apply to DG2 using the same action and
conditions. Add both to the oob rules so they are both reported as
active.

Do not Wa_22012727170 to PVC and MTL since only early A* steppings are
affected.

v2: Remove DG2_G10 from Wa_22012727685 to match current WA database
    (Matt Roper)
v3: GRAPHICS_STEP(A0, FOREVER) can be left alone for DG2 as this means
    all steppings
