// The ArcBridgeHost also registers in Mojo Service Manager by default.
// The lifetime of ArcBridgeHost mojo channel is tied to this instance.
// Also, any ARC related Mojo channel will be closed if ArcBridgeHost Mojo
// channel is closed on error.
// When ARC Instance (not Host) Mojo channel gets ready (= passed via
// OnFooInstanceReady(), and the QueryVersion() gets completed), then this sets
// the raw pointer to the ArcBridgeService so that other services can access
// to the pointer, and resets it on channel closing.
// Note that ArcBridgeService must be alive while ArcBridgeHostImpl is alive.
