[clang-tidy][NFC] Add empty '.clang-tidy' file in tests dir to silent warnings in IDE

[vbvictor]

When working on tests, clangd with option --clang-tidy will report warnings from root clang-tidy config.
I believe these warnings serve no purpose in tests, so we better disable them to silent warnings in IDE.

This is mostly just a hypothesis for now.

I think the Windows build fails because clang-tools-extra/test/clang-tidy/infrastructure/Inputs/param/parameters.txt incorrectly uses single quotes for the -checks argument.

On Windows, the argument is parsed as a check named ' -*,llvm-namespace-comment ', which matches no existing checks, so no checks are enabled via the command line.

Previously, the test passed because it fell back to the root .clang-tidy configuration which enables llvm-*.

I opened #171033 to fix this. @vbvictor can you try manually applying the fix to parameters.txt and see whether the test passes?

Will be good idea to change commit summary to end with to silent warnings in IDE.

Yes, also missed that my title was bad initially.
