Module features

Tidy check to ensure that unstable features are all in order.

This check will ensure properties like:

• All stability attributes look reasonably well formed.
• The set of library features is disjoint from the set of language features.
• Library features have at most one stability level.
• Library features have at most one since value.
• All unstable lang features have tests to ensure they are actually unstable.
• Language features in a group are sorted by feature name.
