[roll] Roll fuchsia [fdf] Add resource-bound composite driver test

Add an integration test to verify composite driver binding where
one of the parent nodes is represented by a driver-provided resource.

The test are follows:
- Implement `RootDriver` to register "left" and "right" instances of the
  test FIDL service, providing "right" via `ProvideResource` and "left"
  as a child node. It then adds a composite spec requiring both.
- Implement `LeafDriver` to bind to the composite node, connect to both
  parent services, and verify that the expected values are returned
  before signaling success to the test waiter.
- Add a Rust integration test suite that configures and launches the
  driver test realm to verify the end-to-end binding and communication.
