  [mlir][XeGPUToXeVM][XeVMToLLVM] Update the default cache-control values. (#190954)

In XeGPU, user can provide cache control value for only certain levels,
they do not have to provide cache-control value for all levels. However,
XeVM requires that each cache level must have a cache-control value. To
solve this issue, XeGPUToXeVM conversion pass adds default value to
cache-levels that does not have a user-provided cache-control value.

This PR updates this process in the following way:
- If no cache-control hint is provided for any levels, use system
default (USE_DEFAULT).
- If any of the levels has at least one cache-control value, use certain
default value for other levels.

If system default (USE_DEFAULT) is used, no cache-control metadata
annotation is necessary.
