[CFE] Widget tracking for extension method widget factories
This CL extends the widget tracking frontend kernel transformer to support tracking the callsites of extension methods that act as widget factories as the creation location of widgets. To enable this support extension methods have to be annotated. Fixes https://github.com/dart-lang/sdk/issues/50067 Originally created by gabriel@terwesten.net in https://dart-review.googlesource.com/c/sdk/+/263380 Change-Id: I6efe8f081263e58659b9c6374542ad8f04361136 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/275901 Reviewed-by: Jens Johansen <jensj@google.com> Commit-Queue: Johnni Winther <johnniwinther@google.com>
