Add textobjects queries (#20924)

Co-Authored-By: Max <max@zed.dev>

Release Notes:

- vim: Added motions `[[`, `[]`, `]]`, `][` for navigating by section,
`[m`, `]m`, `[M`, `]M` for navigating by method, and `[*`, `]*`, `[/`,
`]/` for comments. These currently only work for languages built in to
Zed, as they are powered by new tree-sitter queries.
- vim: Added new text objects: `ic`, `ac` for inside/around classes,
`if`,`af` for functions/methods, and `g c` for comments. These currently
only work for languages built in to Zed, as they are powered by new
tree-sitter queries.
