This PR connects the view ID provided by the rasterizer to `EmbedderExternalViewEmbedder`'s presenting call (see `embedder_external_view_embedder.cc`). This PR also contains a refactor (which actually takes the majority of LOC) that moves the specification of view ID from `PrepareFlutterView` to `SubmitFlutterView`. The `flutter_view_id` parameter in `PrepareFlutterView` was added in https://github.com/flutter/engine/pull/46169. It turns out that we don't need the view ID throughout the preparation phase, so we can delay the specification to submission, which makes it feel cleaner. ### Tests Existing tests are changed to verify that `SubmitFlutterView` receive the correct view ID. The feature that `EmbedderExternalViewEmbedder` sends the view ID to the presenting API is not tested for now, because `EmbedderExternalViewEmbedder` is typically tested in `embedder_unittests`, but it requires the embedder API `AddView`. It will be tested in later changes to `EmbedderExternalViewEmbedder`. [C++, Objective-C, Java style guides]: https://github.com/flutter/engine/blob/main/CONTRIBUTING.md#style
