soc/intel/meteorlake: Implement cleanup and rearm functions

cpu_cl_cleanup() function checks if the SOC supports storage-off
feature. This feature allows to turn off PUNIT SSRAM to save power.
Enable the storage-off if it's supported. Enabling it also clears the
crashlog records from PUNIT SSRAM.

cpu_cl_rearm() function rearms the CPU crashlog.

BUG=b:262501347
TEST=Able to build google/rex. Verified both features get asserted.
