[clang-tidy] Fix thread_local false positives in misc-use-internal-linkage check (#132573)
Based on C++ standard (see issue
https://github.com/llvm/llvm-project/issues/131679) and
[StackOverflow](https://stackoverflow.com/questions/22794382/are-c11-thread-local-variables-automatically-static)
`thread_local` variables are implicitly `static` so we should not
suggest adding `static` on a `thread_local` variables. I'd appreciate if
someone else will confirm this too because reading standard is tricky.

However, many people still use `static` and `thread_local` together:
[github
code-search](https://github.com/search?type=code&q=%22static+thread_local%22+language%3AC%2B%2B).
Maybe disabling warnings on `thread_local` should be made as a flag?
WDYT?

Closes https://github.com/llvm/llvm-project/issues/131679.
