[libc++abi] Add _LIBCXXABI_DISABLE_VISIBILITY_ANNOTATIONS
It's useful to be able to disable visibility annotations entirely; for
example, if we're building libc++abi static to include in another library,
and we don't want any libc++abi functions getting exported out of that
library. This is a generalization of _LIBCXXABI_DISABLE_DLL_IMPORT_EXPORT.
