x86/cqm: Share PQR_ASSOC related data between CQM and CAT

x86/cqm: Share PQR_ASSOC related data between CQM and CAT

PQR_ASSOC MSR contains the RMID used for preformance monitoring of cache
occupancy and memory bandwidth. The upper 32bit of this MSR contain the
CLOSID for cache allocation. So we need to share the information between
the two facilities.

Move the rdt data structure declaration into the shared header file and
make the per cpu data structure containing the MSR values global.
