Emblem minor refactor

[edd]

The Chore

Emblem's components props are base on HTMLImageAttribute, but most of those attributes are ignored, so the props are a little misleading. Prior to #6525, at least width and height were used. Now they're ignored, lets just fix the misleading types

Task

• [ ] Remove base HTMLImageAttribute props
• [ ] Accept title/alt/ other important props
• [ ] Ensure they are properly passed through
• [ ] Transparent by default until icon has loaded (less jank for dark/light themes)
• [x] Enfore circles

Circles are now enforced in the work Madalina did ... but the rest needs Ed
