perf tools: Add support to specify hw event as PMU event term

Browse Source 
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.
