Refactor the mocs/l3cc kunit test to support odd number of entries. This
switches out from the "check the register value" approach to check the
entry value if it makes sense from the register read. This provides an
easier output to reason about and cross check with bspec.
Some code reordering and variable re-use was also done so the 2
functions follow more or less the same logic.

Let's convert the kunit tests that are currently relying on
xe_device_mem_access_{get,put} towards the direct xe_pm_runtime_{get,put}.
While doing this we need to move the get/put calls towards the outer
bounds of the tests to ensure consistency with the other usages of
pm_runtime on the regular paths.
v2: include xe_pm.h in tests/xe_mocs.c and sort the include block
while at it.
