includes, Darwin: Handle modular use for macOS SDKs [PR116827].
Recent changes to the OS SDKs have altered the way in which include guards
are used for a number of headers when C++ modules are enabled. Instead of
placing the guards in the included header, they are being placed in the
including header. This breaks the assumptions in the current GCC stddef.h
specifically, that the presence of __PTRDIFF_T and __SIZE_T means that the
relevant defs are already made. However in the case of the module-enabled
C++ with these SDKs, that is no longer true.
stddef.h has a large body of special-cases already, but it seems that the
only viable solution here is to add a new one specifically for __APPLE__
and modular code.
This fixes around 280 new fails in the modules test-suite; it is needed on
all open branches that support modules.

* ginclude/stddef.h: Undefine __PTRDIFF_T and __SIZE_T for module-
enabled c++ on Darwin/macOS platforms.
