[New utility]: Vertical-align utilities

Vanilla currently provides a utility class for vertical-align ([u-vertical-align--middle](https://vanillaframework.io/docs/utilities/align#vertical-alignment)), but lacks equivalents for other [values](https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align) like top and bottom.
Adding these would make alignment utilities more flexible and ensure consistent handling of inline elements like badges, icons, and form controls across different contexts.

## Visual

## Context

These utilities would be useful in:
- Badges next to labels (aligning text and count consistently).
- Icons inline with text, where alignment sometimes needs to be top or bottom instead of middle.
- Form components (checkboxes, radio buttons, etc.) where inline alignment flexibility is required.

## State

Does this pattern have state?
- No, these are static utility classes.

## Progressive enhancement

A pattern should be designed small screen first. How does this pattern scale up?
- Mobile-first design remains unaffected since vertical-align is a CSS inline property and degrades gracefully.

How will this pattern degrade on less competent browsers?
- On less capable browsers, inline elements will fall back to default alignment (baseline).
