Added Icons and Header Separators to Code Action Widget

[justschen]

• Added icons and separators to help distinguish different code actions from the quickfix, source actions, lightbulb widget (Visually distinguish fixes from non-fixes in lightbulb menu #132109)

FWIW, I think refactors that don't match one of VS Code's known categories might be going missing (it looks like they're added to an "other" group in the code, but I think they're going missing because there's on else/other case here?

vscode/src/vs/editor/contrib/codeAction/browser/codeActionMenu.ts

Line 408 in 4b6ab49

if (CodeActionKind.SurroundWith.contains(new CodeActionKind(String(firstAction)))) {

This was reported at Dart-Code/Dart-Code#4104. I've advised the poster to file an issue here since I don't think it's intended that refactors must match one of these groups (although, some of those missing in this case could be mapped to SurroundWith, which I'll take a look at).

@DanTup That's a great catch - I had removed an initial code snippet which included 'other' code actions that wouldn't be captured, but added in additional checks for source actions, etc.

Will take a look at this immediately!
