[clang-tidy][NFC] Fix various clang-tidy warning on headers 1/N (llvm#165175)

vbvictor · Lukacma · commit 7d426b5596bd · 2025-10-29T11:17:39.000Z
Started running `clang-tidy` on our clang-tidy headers. This part covers
what `clang-tidy` could fix automatically (with `--fix` option).

The main goal is to enable `HeaderFilterRegex:
'clang-tools-extra/clang-tidy/.*'` eventually in config.
