Change of naming `INativeViewHandler.ContainerView`

### Description

I'd like to change naming of a property `INativeViewHandler.ContainerView`

It used in ViewHandlerOfT series

It's actual type name is WrapperView, so i'd like to change naming to `WrapperView` instead of `ContainerView`
because `ContainerView` is existed another places in here
https://github.com/dotnet/maui/blob/963d68563c8499906e64c1d6debc96754a5c1506/src/Core/src/Platform/Android/ContainerView.cs#L10

https://github.com/dotnet/maui/blob/963d68563c8499906e64c1d6debc96754a5c1506/src/Core/src/Platform/iOS/ContentView.cs#L7

So, it makes me difficult to communicate with others.

### (Public) API Changes

# INativeViewHandler

## Properties
### Rename
| API | Description |
| ------------- | ------------- |
| ContainerView -> WrapperView | |

### Usage Scenarios

N/A

### Backward Compatibility

API breaks

### Difficulty

Low

Start with the platform-specific INativeViewHandler and ViewHandlerOfT files linked in the issue for Android, Windows, and iOS, then search for remaining ContainerView references. The change is done when the handler API and its implementations consistently use WrapperView without confusing references to the existing ContainerView types.
