YT-CPPAP-65: Argument groupt hiding

- Added a `hidden` flag and setter to the `argument_group` class. If the flag is set to `true`, the argument group should not be included in the parser's help message.
- Refactored project test building to generate a single testing executable with Doctest suites instead of having multiple test binaries
- Added a `--clang-format-executable` argument to the formatting script
