Improve completion of cfg attributes
The completion of cfg will look at the enabled cfg keys when performing completion. It will also look crate features when completing a feature cfg option. A fixed list of known values for some cfg options are provided. For unknown keys it will look at the enabled values for that cfg key, which means that completion will only show enabled options for those.
