feat(output_targets): remove legacy angular target (#3493)

this commit removes the legacy angular output target from the core
compiler. stencil no longer places framework output targets within the
compiler directly. instead, developers should be using the angular
output target that is maintained by the stencil/ionic framework teams,
located at https://www.npmjs.com/package/@stencil/angular-output-target

Documentation for getting started with the Angular Framework Wrapper can
be found at: https://stenciljs.com/docs/angular

BREAKING CHANGE: Removed the legacy Angular output target. Users should
migrate to https://www.npmjs.com/package/@stencil/angular-output-target
