Fix sampling counter time scales (#33)

* Fix sampling counter time scales

- All perfetto trace events have "begin_ns" and "end_ns" debug fields
- data for thread start and end timestamp in pthread_create_gotcha
- discard samples outside of thread start and end timestamps
- rename "CPU User CPU Time" perfetto counter to "CPU User Time"
- rename "CPU Kernel CPU Time" perfetto counter to "CPU Kernel Time"
- ensure CPU system samples in perfetto are set to zero at end
- backtrace uses comp::wall_clock record() for timestamps (consistency)
- "Peak Memory Usage [Thread X] (S)" renamed to "Thread Peak Memory Usage [X] (S)"
- "Context Switches [Thread X] (S)" renamed to "Thread Context Switches Usage [X] (S)"
- "Page Faults [Thread X] (S)" renamed to "Thread Page Faults Usage [X] (S)"
- "<PAPI_DESC> [Thread X] (S)" renamed to "Thread <PAPI_DESC> [X] (S)"
- samples
