This reverts commit 92ef2b9c.

This requires either runApp() or
WidgetsFlutterBinding.ensureInitialized() to have been called before
using any MethodChannels. Plugins broadly rely on MethodChannels and
right now there's no general requirements that they be constructed
within the runApp call, so the ecosystem breakages from this are broader
than originally thought. Reverting for now.

[web][upstream] Don't register exit/saveCompilationTrace for web platform since they are not available (#37812)

* Don't register N/A services exit/saveCompilationTrace for web platform

This PR fixes an issue where MouseRegion crashes when being passed with closures instead of methods.

It changes how a RenderMouseRegion handles its MouseTrackingAnnotation.

Instead of creating a new annotation every time it becomes active and destroys it when deactivated, it now creates an annotation during the constructor and holds onto it until the end of its lifecycle.
Instead of directly passing the argument callbacks to the annotation, it proxies them using methods.

Fix an issue where MouseRegion will render its children twice.
