perf list: Support matching by topic

Add support in perf list topic to only show events belonging to a
specific vendor events topic. For example the following works now:

  % perf list frontend
  List of pre-defined events (to be used in -e):

stalled-cycles-frontend OR idle-cycles-frontend[Hardware event]

stalled-cycles-frontend OR cpu/stalled-cycles-frontend/ [Kernel PMU event]

  frontend:
dsb2mite_switches.count
 [Decode Stream Buffer (DSB)-to-MITE switches]
dsb2mite_switches.penalty_cycles
 [Decode Stream Buffer (DSB)-to-MITE switch true penalty cycles]
dsb_fill.exceed_dsb_lines
 [Cycles when Decode Stream Buffer (DSB) fill encounter more than 3 
Decode Stream Buffer (DSB)
  lines]
icache.hit
 [Number of Instruction Cache, Streaming Buffer and Victim Cache Reads. 
both cacheable and
  noncacheable, including UC fetches]
  ...
