Chris Bracken e9965b2d07 iOS: Reduce engine/view controller coupling (flutter/engine#57151) ...

Eliminates some cases where `FlutterViewController` was relying on `FlutterEngine` internals:
* `[FlutterEngine shell]`
* `[FlutterEngine platformView]`
* `[FlutterEngine iosPlatformView]`

Instead, `FlutterEngine` now exposes:
* `installFirstFrameCallback:`
* `enableSemantics:withFlags:`
* `notifyViewCreated`
* `notifyViewDestroyed`
* `waitForFirstFrameSync:callback:`

Also fixes a couple cases where we were relying on transitive header includes:
* `FlutterAppController` relied on `FlutterViewController_Internal.h` for `sendDeepLinkToFramework:completionHandler:`

This is a refactoring followup to https://github.com/flutter/engine/pull/57099 that introduces no semantic changes.
