Land a caller's style with its class on field and picker roots

Plan step 38 review: the showcase kept two unlayered width classes
because <x-input> and <x-datepicker> "don't forward style usefully".
They did not: the Phase F rule is that a caller's class and style land
on the component root, and the field family sent class to the field's
root but style to the inner control, where a width sizes nothing.
Input, password, textarea, select and file now pass style to the field
root with class; datepicker and timepicker put it on their root;
<x-group> dropped style entirely and <x-split-button> gave it to the
leading button; <x-search> rendered it twice, on the root and the
input. A textarea given a style also lost its autogrow rows, since
its own style attribute came second and the browser ignores it.
A dataset test renders each component with both and requires them on
the root, once.
