Implement a way to update GGTT using MI_UPDATE_GTT command 
when possible for MTL as a suggested work around for HW bugs,
Wa_13010847436 and Wa_14019519902.

v2: Fix lockdep warning related to GT wakeref vs 
    blitter engine wakeref.

v3: Rearrange patches/diffs to fix code mixups(Andi)

v4: fix ce leak(Oak)

v5: rebase & resend with new "Test-with"

Test-with: 20230918164747.30171-1-nirmoy.das@intel.com
