Problem:

Treesitter highlighting is slow for large files with lots of injections.

Solution:

Only parse injections we are going to render during a redraw cycle.

---

- `LanguageTree:parse()` will no longer parse injections by default and
  now requires an explicit range argument to be passed.

- `TSHighlighter` now parses injections incrementally during on_win
  callbacks for the line range being rendered.

- Plugins which require certain injections to be parsed must run
  `parser:parse({ start_row, end_row })` before using the tree.

Fixes #20419

- And address more type errors.
- Removed the `concat` option from `get_node_text` since it was applied
  inconsistently and made typing awkward.

Revert "refactor(treesitter): delegate region calculation to treesitter (#22553)"

This reverts commit 276b647fdba07bf1762d8dd371c4b655b8a418df.

fix(treesitter): typos _range.lua

Problem:
  Treesitter injections are slow because all injected trees are invalidated on every change.

Solution:
    Implement smarter invalidation to avoid reparsing injected regions.

    - In on_bytes, try and update self._regions as best we can. This PR just offsets any regions after the change.
    - Add valid flags for each region in self._regions.
    - Call on_bytes recursively for all children.
       - We still need to run the query every time for the top level tree. I don't know how to avoid this. However, if the new injection ranges don't change, then we re-use the old trees and avoid reparsing children.

This should result in roughly a 2-3x reduction in tree parsing when the comment injections are enabled.
