Jon Ross-Perkins a196b9840f Run clang-tidy on headers (#3572)
This patches bazel_clang_tidy handling of headers. I found an equivalent
change at https://github.com/erenon/bazel_clang_tidy/pull/13, but that
was [already
rejected](https://github.com/erenon/bazel_clang_tidy/pull/13#issuecomment-1047007424).
Per the criticism, this will result in redundant processing of headers.

The project instead uses `HeaderFilterRegex: ".*"`, but that results in
two problems:

1. When running with `-k`, errors are repeated when a header is included
more than once, which is common.
2. clang-tidy including errors from headers that are included from other
modules (e.g., abseil-cpp); filtering correctly is difficult.

Given the trade-offs and options (including forking), I thought patching
was preferable so long as it remains narrow.

A design is currently maintained in Google Drive. It'll be migrated to markdown once we are confident in its stability.
