On macOS, use Mach port messaging instead of Unix domain sockets for all IPC transport. This makes the transport capable of carrying Mach port rights as message attachments, which is a prerequisite for sending IOSurface handles over the main IPC channel (currently sent via a separate out-of-band path). It also avoids the need for the FD acknowledgement protocol that TransportSocket requires, since Mach port right transfers are atomic in the kernel. Three connection establishment patterns: - Spawned helper processes (WebContent, RequestServer, etc.) use the existing MachPortServer: the child sends its task port with a reply port, and the parent responds with a pre-created port pair. - Socket-bootstrapped connections (WebDriver, BrowserProcess) exchange Mach port names over the socket, then drop the socket. - Pre-created pairs for IPC tests and in-message transport transfer. Attachment on macOS now wraps a MachPort instead of a file descriptor, converting between the two via fileport_makeport()/fileport_makefd(). The LibIPC socket transport tests are disabled on macOS since they are socket-specific.
