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

Browse source

The uncore subsystem for Alder Lake is similar to the previous Tiger
Lake.

The difference includes:
- New MSR addresses for global control, fixed counters, CBOX and ARB.
  Add a new adl_uncore_msr_ops for uncore operations.
- Add a new threshold field for CBOX.
- New PCIIDs for IMC devices.
