perf tools: Add support to specify hw event as PMU event term
Add a way to specify hw event as PMU event term like: 'cpu/event=cpu-cycles/u' 'cpu/event=instructions,.../u' 'cpu/cycles,.../u' The 'event=cpu-cycles' term is replaced/translated by the hw events term translation, which is exposed by sysfs 'events' group attribute. Add parser bits, the rest is already handled by the PMU alias code.
