Clean up suppression of CA1063 and implement IDisposable correctly

[Arlodotexe]

From CommunityToolkit/Tooling-Windows-Submodule#63

One or more components in this repository are suppressing CA1063. To avoid memory leaks in certain edge cases, we should be implementing the full IDisposable pattern and not suppressing this warning.

Affected components:

• CameraHelper
• AdvancedCollectionView
• ExpressionNode (from Animations package)
