switch to clang-format v14

[2bndy5]

Updates reusable CI workflow that checks code formatting.

• uses clang-format v16
• uses bleeding edge of cpp-linter package to field-test the new PR review feature (cpp-linter --format-review).

Also updates the guideline explanations as some (useful) options were only applicable to v13+.

Note

Updates to all nRF24 org repo's .clang-format file is required for consistency.

the new PR review feature

This feature (of cpp-linter python package) will produce a PR review with a patch (to fix format problems) in the review's summary comment and include applicable fixes as suggestions in review comments (specific to lines in the PR diff).

@TMRh20 This one is for you mostly, but it will be a help to anyone that doesn't understand what the CI is trying to say about code formatting.

PS - Having the CI fix formatting and push changes automatically is on my radar (for the cpp-linter pkg), but I have to be mindful of the write access that idea requires.

I'm ready to merge this, but I want to wait till nRF24/RF24Network#218 is merged first. pushing this change to main will also instigate a crusade of PRs to update the .clang-format config files in all repos.

I have created branches in all repos for the upcoming format crusade.
