It is now possible to use the special IPC::File type in message arguments. In C++, the type is nothing more than a wrapper over a file descriptor. But when serializing/deserializing IPC::File arguments, LibIPC will use the sendfd/recvfd kernel APIs instead of sending the integer inline. This makes it quite convenient to pass files over IPC, and will allow us to significantly tighten sandboxes in the future :^) Closes https://github.com/SerenityOS/serenity/issues/3643
