  Log Message:
  -----------
  [clang-tidy] Improve modernize-redundant-void-arg to recognize macro uses

Sometimes a macro invocation will look like an argument list
declaration.  Improve the check to detect this situation and not
try to modify the macro invocation.

Thanks to Nathan James for the fix.

- Ignore implicit typedefs (e.g. compiler builtins)
- Improve lexing state machine to locate void argument tokens
- Add additional return_t() macro tests
- clang-format control in the test case file
- remove braces around single statements per LLVM style guide

Fixes #43791
