Deal with quantifiers appearing on capture's enclosing patterns

Browse source 
- Use a proper enum type for quantifiers.
- Drop quantifiers from `TSQueryStep`, which was not used.
- Keep track of the captures introduced during a pattern parse, and
  apply the quantifier for the pattern to the captures that were
  introduced by the pattern or any sub patterns.
- Use 'quantifier' instead of 'suffix'.
