Fix camera package fails to build with latest Maui version

[ne0rrmatrix]

This pull request focuses on fixing an issue where updating Dotnet Maui to 9.0.120 and updating workloads will prevent Camera package from building successfully. Updates AndroidX Camera NuGet packages to newer versions, and makes minor corrections to UI data bindings.
Dependency Updates:

• Updated AndroidX Camera NuGet packages (Xamarin.AndroidX.Camera.Camera2, Xamarin.AndroidX.Camera.View, Xamarin.AndroidX.Camera.Extensions) from version 1.4.2.2 to 1.5.0, and added Xamarin.AndroidX.Activity.Ktx version 1.11.0 to the Android project.

UI/Data Binding Fixes:

• Corrected the ItemDisplayBinding in CameraViewPage.xaml to properly bind the camera name from the selected camera.

These changes collectively improve the stability and maintainability of the camera features, especially in scenarios where hardware or system APIs may return null values. ### Description of Change ###

Thanks @ne0rrmatrix!

Just FYI - I added some comments in the code regarding these updated Android API Bindings.

Looking at the Android Docs, these Bindings return NonNull which means they never return a nullable object. My guess is that the C# Bindings returning a nullable object was just an oversight in the new .NET for Android bindings.

I've also added the breaking change label since this PR updates our AndroidX.Camera dependencies.

It is an issue I have talked to them about. It showed up around 1.6.x in media3 libraries. Some builders and some parameters currently are all red unless I add them. It will not build atm without those. But hopefully it will be fixed in dotnet 10 or 11.
