* Add support to use Linux kernel perf subsystem via the profiler. * For now the perf configurability is quite limited to just event names. Threading etc. to come later. * Given we want to support variety of different cpu types, number of events list (in addition to the standard set of events) is also limited. * Rather than failing with unsupported feature for non-Linux platforms, it returns zeros for all the event counts. * For now, max event counts is capped at 4, time multiplexing is not allowed. * Threadpool recreate hack is restricted to mobile only - need to add better support for threading in general Differential Revision: [D40238033](https://our.internmc.facebook.com/intern/diff/D40238033/) **NOTE FOR REVIEWERS**: This PR has internal Meta-specific changes or comments, please review them on [Phabricator](https://our.internmc.facebook.com/intern/diff/D40238033/)!

Add support to use Linux kernel perf subsystem via the profiler.
For now the perf configurability is quite limited to just event names. Threading etc. to come later.
Given we want to support variety of different cpu types, number of events list (in addition to the standard set of events) is also limited.
Rather than failing with unsupported feature for non-Linux platforms, it returns zeros for all the event counts.
For now, max event counts is capped at 4, time multiplexing is not allowed.
Threadpool recreate hack is restricted to mobile only - need to add better support for threading in general
