ci: clang-tidy: speed-up clang-tidy

[hmaciak]

This PR is to speed up clang-tidy builds by building only changed files.

Few minor improvements looking at the results on a test PR:

1. clang-tidy version matters for the results, let's add a print with version like we do for clang-format.
2. Check should fail on errors as well, now it passes.
3. An empty line before 'Analyzing' would improve readability.

Hi @hmaciak thank you for these changes. @theComputeKid is away from the office for the next few weeks so he may or may not be able to provide a timely review. I've approved the PR for now. Thanks.
