[cp][ios] Link PlatformView back to semantics tree (#46471) (#46900) Cherry pick https://github.com/flutter/engine/commit/250daadbca517677317277f314ea2a40568eb345 Cherry pick issue https://github.com/flutter/flutter/issues/136552 Description: The PlatformView does not have a semantics container when added to semantics tree, this PR gives it a semantics container to ensure accessibility traversal works. This fixes https://github.com/flutter/flutter/issues/135504, which is a regression of https://github.com/flutter/engine/commit/b8332e3c4870512a941d685d7d375b1d2d62983c Before https://github.com/flutter/engine/commit/b8332e3c4870512a941d685d7d375b1d2d62983c, the traversal works because the PlatformView is added to the accessibilityElements of the FlutterPlatFormViewSemanticsContainer, which implicitly made the FlutterPlatFormViewSemanticsContainer as the PlatformVIew's AccessibilityContainer. Now we use the PlatformVIew as the nativeAccessibility of the FlutterPlatFormViewSemanticsContainer, we need to expilicitly set the container.

Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
