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]
