perf evsel: Add arch_evsel__hw_name()

The commit 55bcf6ef314ae8ba ("perf: Extend PERF_TYPE_HARDWARE and
PERF_TYPE_HW_CACHE") extends the two types to become PMU aware types for
a hybrid system. However, current evsel__hw_name doesn't take the PMU
type into account. It mistakenly returns the "unknown-hardware" for the
hardware event with a specific PMU type.

Add an arch specific arch_evsel__hw_name() to specially handle the PMU
aware hardware event.

Currently, the extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE is only
supported by X86. Only implement the specific arch_evsel__hw_name() for
X86 in the patch.

Nothing is changed for the other archs.
