The SPI declaration for `libdispatch_init` was not attribtued properly.
The result of this omission was an improper reference to the function on
Windows when disaptch is _not_ linked statically. Correct the
declaration by re-using the `DISPATCH_EXPORT` macro to decorate the
declaration with the appropriate DLLStorage as necessary.

This was caught by running the Foundation tests with SPM with a
refactoring of the toolchain layout during the build.

(cherry picked from commit 853b681)

#5177)

This is required as while `posix_spawnattr_init` permits a nullable
type, `posix_spawnattr_setflags` properly expects a non-null parameter.
Unwrap the newly minted spawnattr or abort if the allocation failed.
