Accessibility: Improve the Tags meta box accessibility.
- changes the "X" links in buttons, improves their color contrast ratio and focus style - adds screen reader text "Remove item: + tagname" - uses `wp.a11y.speak()` to give screen reader users feedback when adding/removing tags - makes the `tagcloud-link` toggle a button, with an `aria-expanded` attribute to indicate the tag cloud collapsed/expanded state - changes colors for the autocomplete highlighted option in order to have a better color contrast ratio - reduces the font size for the autocomplete on Press This - removes CSS related to the old `suggest.js` from Press This Props joedolson, cgrymala, azaozz, afercia. Fixes #27555. git-svn-id: https://develop.svn.wordpress.org/trunk@38880 602fd350-edb4-49c9-b593-d223f7449a82
