refactor(treesitter): redesign query iterating

Browse Source 
Problem:

  `TSNode:_rawquery()` is complicated, has known issues and the Lua and
  C code is awkwardly coupled (see logic with `active`).

Solution:

  - Add `TSQueryCursor` and `TSQueryMatch` bindings.
  - Replace `TSNode:_rawquery()` with `TSQueryCursor:next_capture()` and `TSQueryCursor:next_match()`
  - Do more stuff in Lua
  - API for `Query:iter_captures()` and `Query:iter_matches()` remains the same.
  - `treesitter.c` no longer contains any logic related to predicates.
  - Add `match_limit` option to `iter_matches()`. Default is still 256.
