perf/x86: Factor out x86_pmu_show_pmu_cap
The PMU capabilities are different among hybrid PMUs. Perf should dump
the PMU capabilities information for each hybrid PMU.
Factor out x86_pmu_show_pmu_cap() which shows the PMU capabilities
information. The function will be reused later when registering a
dedicated hybrid PMU.
