  Log Message:
  -----------
  [clang-tidy] Fix false positives on C23 enums in `bugprone-signed-char-misuse` (#149790)

Ignore false positives on C23 enums which allows setting the fixed
underlying type to signed char.

The AST tree for C enums includes a ImplicitCastExp
(that was matched) but this is not the case for C++ enums.

Fixes #145651
