Size icons and shapes with a prop instead of a Tailwind class

<x-icon size> writes --md-icon-size (24px by default) and takes the optical-size-20
cut for 20px or less, as M3 asks; mirror-rtl flips a directional symbol. <x-shape
size> writes --md-shape-size. Both draw from plain-CSS stylesheets in
material.components, gathered in components.css until all.css replaces it; a
caller's size class still wins while the other components are rewritten.
Plan steps 35 and 36, the prop every component rewrite depends on.
