Add IPC::TransportHandle as an abstraction for passing IPC transports through .ipc messages. This replaces IPC::File at all sites where a transport (not a generic file) is being transferred between processes. TransportHandle provides from_transport(), clone_from_transport(), and create_transport() methods that encapsulate the fd-to-socket-to-transport conversion in one place. This is preparatory work for Mach port support on macOS -- when that lands, only TransportHandle's internals need to change while all .ipc definitions and call sites remain untouched.
