perf script: Add --show-bpf-events to show eBPF related events

Add the --show-bpf-events command line option to show the eBPF related events:

  PERF_RECORD_KSYMBOL
  PERF_RECORD_BPF_EVENT

Usage:

  # perf record -a
  ...
  # perf script --show-bpf-events
  ...
  swapper     0 [000]     0.000000: PERF_RECORD_KSYMBOL ksymbol event with addr ffffffffc0ef971d len 229 type 1 flags 0x0 name bpf_prog_2a142ef67aaad174
  swapper     0 [000]     0.000000: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 36
  ...

Committer testing:
