feat(markdown)!: switch to split parser (#3048)

* switch to split markdown parser with separate block and inline parsers to improve performance
* add exclude_children! directive (useful for something like Injected markdown incorrectly highlights indented docstrings #2212)
* split markdown queries into block and inline ones and add the injection for inline into block grammar
* add include_dir option to parser configs (needed because the two grammars don't live in the repos root directory)

BREAKING CHANGE: downstream queries need to be adapted to new parser
