fixes #94677

Fixes #22353

StatusBarItem is one of the few places in our API where we only allow extensions to give us a command as a `string` instead of as `Command` object. This change updates the API to also allow passing in a `vscode.Command` (which also allows arguments!)

Const provides better type guards and can make logic clearer

We compile using the alwaysStrict flag so these directives are not needed.

This part removes most of the remaining use strict directives that were not caught by part 1 and 2
