perf/x86/intel/cqm: Add storage for 'closid' and clean up 'struct intel_pqr_state'

'closid' (CLass Of Service ID) is used for the Class based Cache
Allocation Technology (CAT). Add explicit storage to the per cpu cache
for it, so it can be used later with the CAT support (requires to move
the per cpu data).

While at it:

 - Rename the structure to intel_pqr_state which reflects the actual
   purpose of the struct: cache values which go into the PQR MSR

 - Rename 'cnt' to rmid_usecnt which reflects the actual purpose of
   the counter.

 - Document the structure and the struct members.
