Pull Request Overview
Updates AppThemeResourceExtension to remove its reliance on the internal IProvideParentValues interface by introducing a custom resource lookup that leverages IProvideValueTarget, IRootObjectProvider, and application‐level resources.
- Replaced the
RequireServiceattribute to useIProvideValueTargetandIRootObjectProvider. - Reimplemented
ProvideValueto search resources via visual tree traversal, root object, then application resources. - Added
TryFindResourceInVisualElementhelper and adjusted exception messages; also fixed a typo inAppThemeObject.shared.cs.

- The summary only mentions visual tree traversal, but the method also checks the element itself for
IResourcesProviderand supportsResourceDictionarylookups. Update the doc comment to accurately describe all lookup paths.
/// Attempts to locate a resource by walking up the visual tree from a target object.

Description of Change
This PR updates
AppThemeResourceExtensionto not useIProvideParentValues, which is internal to .NET MAUI.At the .NET MAUI side we're exploring to remove the InternalsVisibleTo for the Toolkit since it shouldn't be necessary.
Most APIs there will be removed with the Popup v2 implementation (yay), the rest are being used in AvatarView and we're OK to make those public on the .NET MAUI side for .NET 10, but the one used in
AppThemeResourceExtensionwe're not OK with making public.Therefore, this PR explores an alternative implementation that does not use
IProvideParentValues
