This is an umbrella bug for the work required to build a Swift version of the Web Back Forward List. RATIONALE: WebKit wishes to use Swift to provide much stronger memory safety in its most sensitive attack surface: CoreIPC message handlers. This PR prototypes how we can convert a single, simple, message handler to Swift. In itself, converting this message handler provides negligible security benefit (in fact, rewrites usually introduce extra bugs) but having a message handler in Swift paves the way for future work - in particular, it ensures that any future new subsystems can be written in Swift rather than C++. BUILDING: By default this change has no effect. If the LocalOverride option: ENABLE_BACK_FORWARD_LIST_SWIFT=ENABLE_BACK_FORWARD_LIST_SWIFT is given, then a Swift version of the WebBackForwardList will be used. It is intended to be functionally the same as the C++ version. A recent SDK will need to be used.
