perf tools: Implement branch_type event parameter
It can be useful to specify branch type state per event, for example if we want to collect both software trace points and last branch PMU events in a single collection. Currently this doesn't work because the software trace point errors out with -b. There was already a branch-type parameter to configure branch sample types per event in the parser, but it was stubbed out. This patch implements the necessary plumbing to actually enable it. Now: $ perf record -e sched:sched_switch,cpu/cpu-cycles,branch_type=any/ ... works.
