Darwin, fixincludes: Handle MacOS13 SDK Apple-specific deprecations [PR107568].

The SDK for MacOS13 includes Apple-specific deprecations of some functions that
are not deprecated in Posix, C or C++ and widely used in GCC.

The fix makes the deprecation conditional on __APPLE_LOCAL_DEPRECATIONS so that
end users may still observe them but they are hidden from normal compilations.

Signed-off-by: Iain Sandoe <[email protected]>

	PR target/107568

fixincludes/ChangeLog:

	* fixincl.x: Regenerate.
	* inclhack.def: Add a fix for MacOS13 SDK function deprecations
	in stdio.h.
	* tests/base/stdio.h (__deprecated_msg): New test.
