[Dev only] Migrate C++ Format Settings to clang-format

[akuker]

The resulting change from #1260 was to tie the code formatting to a specific set of editors (Eclipse and/or JIdea). From a quick search, I wasn't able to find a way to run this formatter from the CLI without installing Eclipse.

Recommend a clang-formatter configuration be implemented as discussed in the original ticket. Older clang-format configuration is available here: https://github.com/PiSCSI/piscsi/blob/v23.04.01/cpp/.clang-format
