Support TreeSitter parser in several text-objects

[t9md]

New TreeSitter will become default in next Atom release. But vmp is not yet prepared for it.

TODO

need check

• How scope name is different.
• Is there any way to detect particular editor is using TreeSitter?
  • Since not all grammar is TreeSitter supported.
• Logic
  • Determine editor's parser whether it's old or new TreeSitter based.
  • Then switch scope set to use for
  • function determination(text-object)
  • string(motion by scope for string?)
  • number(motion by scope for number?)
  • Anything else?

need fix

• [x] Fold text-object: conjoined text-object
• [x] Function text-object
• [x] block-comment(inline) text-object
• [ ] scope-based motion
