Harlan Haskins 24c35f3ff1 [ModuleInterface] Error for out-of-date modules in the resource-dir (#24139) ...

If we're loading a .swiftmodule from the resource dir adjacent to the compiler,
defer to the serialized loader instead of falling back. This is mainly to
support development of Swift, where one might change the module format version
but forget to recompile the standard library. If that happens, don't fall back
and silently recompile the standard library -- instead, error like we used to.
