sys/fuchsia: describe method response types & handles; add support for union

* create a response handle structure for each FIDL method
* generate zx_channel_write for requests having no response
* generate zx_channel_read for events (no request but just response)
* translate FIDL union types to syzkaller union types
  (see fuchsia_io_ObjectInfoHandles)
