Fixes issues such as * https://github.com/flutter/flutter-intellij/issues/814 * https://github.com/dart-lang/sdk/issues/33957 . Essentially, in Flutter, it's often useful to create a new context in the UI/widget tree as a place to begin a search towards the trunk of the tree for various state structures attached to lower levels of the tree. The basic `Builder` widget is the official means for creating such a context/entry-point. The patches in this PR are essentially a copy-paste-tweak from two types of existing, similar assists. The main origin was taken from `FlutterWrapStreamBuilder` which wraps client code with a constructor for the StreamBuilder sub-class. The new assist, provided here, is a little more basic/general than the StreamBuilder so it was able to also adopt assertion and test code from some of the other assists for basic widgets.
