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.
