perf/x86: Print PMU counters bitmap in x86_pmu_show_pmu_cap()

Along with the introduction Perfmon v6, pmu counters could be
incontinuous, like fixed counters on CWF, only fixed counters 0-3 and
5-7 are supported, there is no fixed counter 4 on CWF. To accommodate
this change, archPerfmonExt CPUID (0x23) leaves are introduced to
enumerate the true-view of counters bitmap.

Current perf code already supports archPerfmonExt CPUID and uses
counters-bitmap to enumerate HW really supported counters, but
x86_pmu_show_pmu_cap() still only dumps the absolute counter number
instead of true-view bitmap, it's out-dated and may mislead readers.

So dump counters true-view bitmap in x86_pmu_show_pmu_cap() and
opportunistically change the dump sequence and words.
