Move the SC constants for macos to an accessible module (fixes #24374 for mac).
Move the SC constants for macos to an accessible module (fixes #24374 for mac).

These constants were added in 6f54ce9aa5d2baf0cd82c01e2c181ab17439b7d7 and
e8fbd1ce048fdfc2db1d446fedfe8775ce446046 to a consts module that is behind a
gate.

I have not confirmed that these constants do indeed work on either OSX or iOS.

It appears that some of the constants may actually belong in a POSIX module,
but I didn't make these changes here because I don't have access to the POSIX
standard.
