Reworked internals of formatting to better align to vscode's best practices. Also leverages some internal techniques to improve formatting performance

The result of this pr is a full file save format running in ~10ms. This provides a much improved DX, similar to that of using the default dart format functionality. Example of this running is as follows:

Due to adhering to the registerDocumentFormattingEditProvider we're also able to tap into vscodes default formatting functionality. This means the "Format Document" action/hotkey should work out of the box (with eventual support for "format selection", and "format modified lines")

Because of these changes, some configuration settings will need to be updated, and as such, this PR is a major. The changes to settings.json are as follows:

// disable Dart-Code's formatter
"dart.enableSdkFormatter": false,

"[dart]": {
  // Specify the default formatter to use this extension
  "editor.defaultFormatter": "Workiva.over-react-format-on-save",
  
  // Optionally enable "formatOnSave"
  "editor.formatOnSave": true
},
