Implement support for clang extra tools

[bobbrow]

Copied from #2908 which is being repurposed to cover just clang-tidy.

Implement support for clang extra tools:

clang-include-fixer
clang-refactor
clang-analyzer
clang-rename

[mrx23dot]

There is already an addon for each, e.g.
https://marketplace.visualstudio.com/items?itemName=xaver.clang-format

no point bloating the main addon.

please close.

@mrx23dot https://marketplace.visualstudio.com/items?itemName=xaver.clang-format was updated 2019 last time, and VS Code C/C++ extension already supports Clang Format. This topic is about supporting the other Clang extra tools as part of clang.
