perf/x86/intel/uncore: Add Nova Lake support
Nova Lake uncore PMON largely follows Panther Lake and supports CBOX,
iMC, cNCU, SANTA, sNCU, and HBO units.
As with Panther Lake, CBOX, cNCU, and SANTA are not enumerated via
discovery tables. Their programming model matches Panther Lake, with
differences limited to MSR addresses and the number of boxes or counters
per box.
The remaining units are enumerated via discovery tables using a new
base MSR (0x711) and otherwise reuse the Panther Lake implementation.
Nova Lake also supports iMC free-running counters.
