Support for tracing mutex locking (#52)
* Parallel overhead example with locks
* Support tracing mutex locking + more
- support wrapping pthread_mutex_lock
- support wrapping pthread_mutex_unlock
- support wrapping pthread_mutex_trylock
- get_perfetto_combined_traces setting
- OMNITRACE_TRACE_THREAD_LOCKS option
- ThreadState
- critical trace includes queue id
- enabled/disabled settings in timemory
- fix OMNITRACE_TIMEMORY_COMPONENTS
- fix reading config
- fix setting categories
- applied ThreadState::Internal in various places
- utility::get_filled_array
- utility::get_reserved_vector
- utility::get_thread_index
- fork_gotcha messages about forks
- split out some pthread_gotcha functionality into pthread_create_gotcha
- handle queue id in roctracer callbacks
* Update timemory and PTL submodules
* Misc CMake updates
- Includes fix to omnitrace-static-lib{gcc,stdcxx}
* Misc cleanup to pthread_mutex_gotcha and backtrace
* Fix to duplicate field in module_function json
* Improvement to debug messages
* omnitrace-dl and common improvements
- tweak to delimit
- common::ignore message
- common::join quoting of strings
- omnitrace_set_env ignores if inited and active
- omnitrace_set_mpi ignores if inited and active
* nsync for transpose example
* Fix to thread_deleter<void> functor invoke
* Fix thread state and HIP stream enums
