perf/x86/rapl: Move the cntr_mask to rapl_pmus struct

Prepare for the addition of RAPL core energy counter support.

Move cntr_mask to rapl_pmus struct instead of adding a new global
cntr_mask for the new RAPL power_core PMU. This will also ensure that
the second "core_cntr_mask" is only created if needed (i.e. in case of
AMD CPUs).
