Move repeated declarations from size/variant-specific selectors to base classes, reducing compiled CSS output: - icon: box-sizing and vertical-align to .icon base class - spinner: remove redundant box-sizing from size loop (already on .root) - tiles: remove redundant box-sizing from column loop (already on .tile-container) - button: hoist text-decoration and position to .button base class Total savings: ~1.3KB across affected components.

Description
I noticed that some CSS declarations were being repeated in loops. For example, the class for each icon size has the same
box-sizingandvertical-aligndeclarations.This PR moves those declarations to avoid repetition, reducing the amount of generated CSS by ~1.3KB (total) across the icon, spinner, tiles, and button components.
How has this been tested?
Since this is purely a CSS change, the screenshot tests (which I don't have the ability to run) should be definitive.
