Property Editor supports refactors

The property editor should expose the supported refactors for the selected widget

With https://dart-review.googlesource.com/c/sdk/+/428784, it's possible to call textDocument/codeActions over DTD and you will get back a list of Commands that can be invoked using workspace/executeCommand.

Here's an example script you can run in VS Code (make sure you update the DTD URI!) that connects to DTD and lets you execute these:

It only requests actions of kind refactor.flutter.wrap so you'll only see the Wrap actions.

I did find one slight issue which is for CodeActions we usually support a non-standard snippet syntax for VS Code (we're still waiting for the standard LSP version to be released) but it doesn't work here, so using "Wrap with widget" will result in snippet markup appearing in the editor where we'd normally set the selection. I'll work on a fix for that (which unfortunately will mean not selecting the "widget" text as we would from a code action).

Thank you! Looking forward to trying this out
