(treesit--indent-rules-optimize): Optimize 'and' and 'or' matcher forms

* lisp/treesit.el (treesit--indent-rules-optimize):
Optimize 'and' and 'or' matcher forms.  When 'and' has a 'query'
matcher inside (as is the case in ruby-ts--indent-rules, many
times over), this yields a significant performance boost.
