[committed] d, darwin: Add Apple as a predefined version

[Iain Buclaw]

Hi,

This patch adds a new predefined version identifier intended to be
turned on if any of the OSX, iOS, TVOS, WatchOS, or VisionOS versions
are predefined.

Regstrapped on x86_64-linux-gnu, committed to mainline.

Regards,
Iain.
