Now that LibIPC uses Mach ports for transport on macOS, IOSurface port rights can be sent as regular IPC message attachments instead of through a separate ad-hoc Mach message side-channel. Introduce Web::SharedBackingStore that wraps either a MachPort (macOS) or ShareableBitmap (other platforms) with IPC encode/decode support, unifying backing store allocation into the existing did_allocate_backing_stores IPC message.
