CppEditor: Avoid blocking context menu invocation

Browse Source 
Show the menu always immediately.

If the needed use selections are not up to date for the refactoring
actions, then trigger an async run and if that one finishes, then update
the refactoring menu. In the meanwhile, show a place holder menu item
showing on-going progress (Utils::ProgressIndicator).
