We used to allow @objc enums on Linux, where Objective-C interop is disabled, because the check first looked for an import of the Foundation module (which could be the non-Objective-C corelibs-foundation) before checking if Objective-C interop was enabled. Since @objc enums don't actually depend on Foundation or Objective-C and only have a different layout in IRGen, let's bring back and formalize the old behavior. Fixes https://bugs.swift.org/browse/SR-14548 / rdar://problem/77325078.
