Remove the deprecated patternStates object on patternlab-config.json

[bmuenzenmeyer]

The frontmatter/markdown state solution has been in place for a while now, with deprecation warnings emitted by the library.

It's time to remove the old functionality.

• Remove patternStates from all patternlab-config.json files across repos
• Remove all signs of setState() within pattern_assembler.js as parsePatternMarkdown() does all the work now.
• Resolve any unit tests

I can give this a shot tonight

@bmuenzenmeyer Does patternStateCascade also need to be removed from patternlab-config.json

[bmuenzenmeyer]

the cascade is still used.
relevant code: https://github.com/pattern-lab/patternlab-node/blob/master/core/lib/lineage_hunter.js#L117
