perf/x86/intel/uncore: Add Meteor Lake support



The uncore subsystem for Meteor Lake is similar to the previous Alder
Lake. The main difference is that MTL provides PMU support for different
tiles, while ADL only provides PMU support for the whole package. On
ADL, there are CBOX, ARB, and clockbox uncore PMON units. On MTL, they
are split into CBOX/HAC_CBOX, ARB/HAC_ARB, and cncu/sncu which provides
a fixed counter for clockticks. Also, new MSR addresses are introduced
on MTL.

The IMC uncore PMON is the same as Alder Lake. Add new PCIIDs of IMC for
Meteor Lake.
