Sergey Biryukov b3bb99b3d7 Twenty Twenty-One: Clean up Button styles.
This change restructures the Button element styles for better a11y and expected color behaviors. Here what has changed:

- The `button-style()` mixin is now the ''single source or truth'' for how Button should look site-wide.
  - Button Block, File Block, and Search form Blocks all rely on this one mixin.
  - The same styles is also applied to the `<button>` element which appears in widgets, the 404 search form and comments form.
- Improves expected button styles for various conditions and contexts as follows: 
  - User color palette selections for Buttons are retained regardless of a parent block’s color settings or dark-mode.
  - Supports both Default/Filled styles and Outline styles.
  - More consistent `:hover` and `:active` styles.
  - `:focus` styles are now always visible and legible.
- Adds a `--local-color` color variable to scope color relationships to nested blocks.
- Reduces selectors in `style.css` output.
- 1:1 experience between editor and front end button styles.
- Properly supports Dark-mode.
