drm/xe/guc: Enable WA_DUAL_QUEUE for newer platforms

The DUAL_QUEUE_WA tells the GuC to not allow concurrent submissions
on RCS and CCSes with different address spaces, which on DG2 is
required as a WA for an HW bug. On newer platforms, this block has
been moved in HW at the CS level, by stalling the RCS/CCS context
switch when one of the other RCS/CCSes is busy with a different
address space. While functionally correct, having a submission
stalled on the HW limits the GuC ability to shuffle things around and
can cause complications if the non-stalled submission runs for a long
time, because the GuC doesn't know that the stalled submission isn't
actually running and might declare it as hung. Therefore, we enable
the DUAL_QUEUE_WA on all newer platforms to move management back to
the GuC.

Note that the GuC specs also recommend enabling this for all platforms
starting from MTL that have a CCS.

v2: only apply the WA on GTs that have CCS engines
v3: split comment (Jonathan)
