Layer the token files and keep their utilities apart

Plan step 33. Each token file now opens with the material layer
statement and wraps its declarations in material.tokens (the font face
in material.base), so an application's unlayered scheme outranks the
package default whatever the selectors, and the foundation can import
the files with no layer() on the import.

The type-* and state utilities move to tokens/utilities.css, still
imported by material.css, so no file the foundation imports carries a
Tailwind directive. [x-cloak] moves beside the [hidden] rule in
foundation/hidden.css, outside every layer; material.css imports it.
