Extracts the parser to `@handlebars/parser`, where it can be shared between different implementations. This means that e.g. Glimmer/Ember will be able to iterate on new features without forcing Handlebars to adopt them immediately, and vice versa. All implementors will be able to absorb changes as it makes sense for them.
