Adding SARIF result format support for clang-tidy

[shaopeng-gh]

Hello! We are interested in adding support for output in the open-standard SARIF format to the clang-tidy, if not yet implemented. SARIF support is required to integrate it in GitHub code scanning. Doing so would make it available to every repo in GitHub.

More about SARIF here:
What is SARIF?
Why SARIF?

If you agree, we will be happy to looking into necessary code changes and provide guidance on creating a workflow to make it available as a GitHub code scanner.

Thanks,
Shaopeng

Here is a third-party tool that converts clang-tidy output to sarif:
