Pull Request Overview
This PR fixes a code generation issue in the XAML source generator related to double casting when adding items to collections. The fix addresses 3 failing tests that were experiencing issues with OnPlatform functionality by properly handling intermediate implicit conversions during collection item addition.
- Removes conditional compilation directives from test methods that were limiting test parameter values
- Adds logic to detect and handle double implicit conversions in the source generator's Add method
- Ensures proper casting chain when adding items to collections that require intermediate type conversions

The method HasDoubleImplicitConversion is called but not defined in this file or visible in the diff. This will cause a compilation error unless this method exists elsewhere in the class or is imported.
