cmake: more syntax tidy-up
- quote string literals.
  In the hope it improves syntax-highlighting and readability.

- use lowercase, underscore-prefixed local var names.
  As a hint for scope, to help readability.

- prefer `pkg_search_module` (over `pkg_check_modules`).
  They are the same, but `pkg_search_module` stops searching
  at the first hit.

- more `IN LISTS` in `foreach()`.

- OtherTests.cmake: clear `CMAKE_EXTRA_INCLUDE_FILES` after use.

- add `PROJECT_LABEL` for http/client and unit test targets.

- sync `Find*` module comments and formatting.

- drop a few local variables.

- drop bogus `CARES_LIBRARIES` from comment.

- unquote numeric literal.

Follow-up to acbc6b703f #14197
Closes #14388
