restructure libomnitrace + tasking and omnitrace-causal updates (#237)

* restructured libomnitrace

- this is necessary to incorporate some of the binary analysis capabilities into omnitrace exe
- created libomnitrace-core (static)
- created libomnitrace-binary (static)
- created libomnitrace (static)
- omnitrace-avail links to libomnitrace.a
- omnitrace-critical-trace links to libomnitrace.a
- tweaked the testing
  - reduced verbosity on some of MPI tests
  - excluded trace-time-window from tests on Ubuntu 18.04
  - reduced causal e2e iterations
- minor tweak to tasking
  - manually create `PTL::UserTaskQueue` instance instead of relying on `PTL::ThreadPool` to create it

* Update formatting workflow

- source formatting uses ubuntu-22.04
- check-includes doesn't generate false positive for 'include "timemory.hpp"'

* omnitrace-causal --generate-configs

- fix config generation in omnitrace causal
- add test for omnitrace-causal + generating configs

* Fix omnitrace-object-library build

- accidentally included rocm sources in non-rocm builds

* Fix rocm compilation w/o rocprofiler

* update timemory submodule with mpi_get warning messages

* sampling offload file updates

- more verbose messages
- disable offload before stopping

* testing updates

- increase causal e2e iterations to 12
- increase lock_environment verbose to 2 (for sampling offload messages)
- fix return for omnitrace_add_validation_test
