preprocessor: Make __has_include a builtin macro [PR93452]
The clever hack of '#define __has_include __has_include' breaks -dD
and -fdirectives-only, because that emits definitions. This turns
__has_include into a proper builtin macro. Thus it's never emitted
via -dD, and because use outside of directive processing is undefined,
we can just expand it anywhere.
