Now `:InspectTree` will show missing nodes as e.g. `(MISSING identifier)`
or `(MISSING ";")` rather than just `(identifier)` or `";"`. This is
doable because the `MISSING` keyword is now valid query syntax.

When given, only that range will be checked for validity rather than the
entire tree. This is used in the highlighter to save CPU cycles since we
only need to parse a certain region at a time anyway.

Breaking change: `ts_node_child_containing_descendant()` was removed

Breaking change: tree-sitter 0.25 (HEAD) required

**Problem:** `vim.treesitter.get_parser()` and `vim.treesitter.start()`
both parse the tree before returning it. This is problematic because if
this is a sync parse, it will stall the editor on large files. If it is
an async parse, the functions return stale trees.

**Solution:** Remove this parsing side effect and leave it to the user
to parse the returned trees, either synchronously or asynchronously.

**Problem:** Parsing can be slow for large files, and it is a blocking
operation which can be disruptive and annoying.

**Solution:** Provide a function for asynchronous parsing, which accepts
a callback to be run after parsing completes.

**Problem:** Query parsing uses a weak cache which is invalidated
frequently

**Solution:** Make the cache strong, and invalidate it manually when
necessary (that is, when `rtp` is changed or `query.set()` is called)
