Log:
unwind: remove last instance of -Wexpansion-to-defined
This unifies the definition of _LIBUNWIND_BUILD_SJLJ_APIS. It also further
generalises the definition to allow building these APIs on non-Apple targets
when `-fsjlj-excceptions` is used. The header is now clean of macros which
expand to defined checks.
