Beautifier: ClangFormat: Format current syntactic entity for no selection

In case there was no selection, the action "Format Selected Text" could
format the whole file (option) as a fallback.

However, there is also the use case of formatting the syntactic entity
under the cursor. Introducing another separate action for this feels
wrong, so remove the fallback instead since there is already an action
handling this.
