rocprofiler library unit tests (#81)

* Update CI and linting workflows

- delete linting workflow
- compile default CI job with clang-tidy
- split out code coverage matrix entry to separate job
- code coverage job runs code coverage 3x
  - once for total code coverage
  - once for unittests code coverage
  - once for samples code coverage

* Update PTL submodule

- improves handling of when thread pool is destroyed in atexit handler

* Update lib/rocprofiler/buffer

- buffer::instance::get_internal_buffer()
- allocate_buffer invokes internal_threading::initialize() on first entry
- update flush routine
 - if wait is false, does not wait for task group to finish syncing
 - checks for callback pointer

* Update lib/rocprofiler/internal_threading

- modifications to handle destruction of statics before atexit handler is invoked

* Update lib/rocprofiler/registration.cpp

- reorder atexit call in initialize()
- protect finalize from executing more than once

* Add unittests for rocprofiler buffer

* Update CI workflow

- disable fail-fast for sanitizers
- move AddressSanitizer job to top of the list

* Update lib/rocprofiler/tests/buffer/CMakeLists.txt

- do not set memcheck LD_PRELOAD for rocprofiler-lib-buffer-tests

* Update lib/rocprofiler/registration.{hpp,cpp}

- only invoke client finalizers if initialized
- remove invoke_client_initializer
- move invoke_client functions to anonymous namespace (no declaration in header)
- set fini status in finalize

* Update scripts/thread-sanitizer-suppr.txt

- suppress false positive for double mutex lock in external/ptl/source/PTL/TaskGroup.hh

* Restructure lib/rocprofiler/tests

* Update lib/common

- add utility.cpp
- move read_command_line to utility.{hpp,cpp}
  - was formerly in config.cpp

* Update lib/rocprofiler

- checks for init status return configuration locked if status is not greater than -1
  - in other words, this prevents calling these functions directly (which was possible when check was for greater than 0

* Update lib/rocprofiler/context/context.{hpp,cpp}

- provide deactivate_client_contexts and deregister_client_contexts
  - these functions are used when the tool fails to configure

* Update lib/rocprofiler/registration.{hpp,cpp}

- internal "public" get_client_offet()
- client ids are offset by a random value to avoid default values behaving correctly

* Update lib/rocprofiler/tests

- fix rocprofiler_lib.registration_lambda_no_result

* Update lib/rocprofiler/tests

- fix rocprofiler_lib.registration_lambda_with_result

* Update lib/rocprofiler/tests

- remove deep bind from rocprofiler_lib.registration_lambda_with_result

* Update lib/rocprofiler/tests

- use RTLD_NOW when dlopen'ing in rocprofiler_lib.registration_lambda_with_result

* Update rocprofiler registration tests

- split registration tests into separate exe that links to shared library

* Formatting

* Update CI workflow

- always checkout submodules via actions/checkout

* Update lib/rocprofiler/buffer.{hpp,cpp}

- fix issue with buffer flushing not working when only called once

* Update rocprofiler lib registration test

- test for buffered callback

* Update include/rocprofiler/rocprofiler.h

- include internal_threading.h header

* Update rocprofiler lib registration test

- add in internal threading for buffered test
