platform/x86/intel/pmc: Enable PkgC LTR blocking counter

Browse source

Enable the Package C-state LTR blocking counter in the PMT telemetry
region. This counter records how many times any Package C-state entry
is blocked for the specified reasons.

Add pmc_core_pkgc_counters_show() as a common helper to display
package C-state blocking counters from the telemetry region.
