vim: Add AnyQuotes support for unified quote handling similar to mini.ai nvim (#22263)

### Edit 1:
I tested it locally and it works!

### IMPORTANT: 
**Feedback and suggestions for improvement are greatly appreciated!**

This commit introduces a new AnyQuotes text object to handle text
surrounded by single quotes ('), double quotes ("), or back quotes (`)
seamlessly. The following changes are included:

- Added AnyQuotes to the Object enum to represent the new feature.
- Registered AnyQuotes as an action in the actions! macro and register
function to ensure proper integration with Vim actions like ci, ca, di,
and da.
- Extended Object::range to check for surrounding single, double, or
back quotes sequentially.
- Updated methods like is_multiline and always_expands_both_ways to
ensure consistent behavior with other text objects.
- Added support in surrounding_markers to evaluate any of the quote
types when AnyQuotes is invoked.
- This enhancement provides users with a flexible and unified way to
interact with text objects enclosed by different types of quotes.

Release Notes:

- vim: Add `aq`/`iq` "any quote" text objects that are the smallest of
`a"`, `a'` or <code>a`</code>
