* Update external/CMakeLists.txt

- checkout submodule if not already checked out or clone repo if no .gitmodules file
- find_package(... REQUIRED)

* Disable tests from external directory

* Update external/CMakeLists.txt

- fix type: BRANCH -> REPO_BRANCH

* Update cmake/rocprofiler_register_formatting.cmake

- Include external/CMakeLists.txt in format-cmake target
- include format-cmake in format target

* Fix cmake options

- ROCPROFILE_REGISTER_* -> ROCPROFILER_REGISTER_*

* Update rocprofiler_register_linting.cmake

- fix header filter to exclude external headers
- enable warning-as-errors except for misc-header-include-cycle because that originates in fmt headers

* Fix clang-tidy error in utility.cpp

- a bit out of place in this PR but caught due to --warning-as-errors addition
