Problem Description

There is a ensureXAMLDialect() function in autolinkWindows.ts that allowed devs to configure their old architecture project to specify useWinUI3 in their react-native config file and let it overwrite the value set in ExperimentalFeatures.props.

This feature is confusing and unnecessary, as we no longer support using WinUI3 in Old architecture projects, nor is it optional in New Architecture projects.

Furthermore, the autolink tests for this feature fail because it was broken with the removal of allowing users to set the WinUI3 value for new Old Architecture projects.

Steps To Reproduce

  1. Open packages/@react-native-windows/cli
  2. Run yarn test autolink
