Add the row layout component

Plan step 35: <x-row gap align justify wrap stack-below>, children side
by side in a pane and stacked under one another below an M3 breakpoint,
in the inline direction so a right-to-left document mirrors it.

* bidirectionality rules ask of every layout (docs/reference/m3/foundations.md § Layout
* Bidirectionality / RTL). Children are centred across the row unless `data-md-align` says
* `start`, `end`, `stretch` or `baseline`; `data-md-justify` places them along it (`start`,
* `center`, `end`, `between`); `data-md-wrap` lets them wrap. The space between them is `--md-gap`
* (spacing.css).
*
* `data-md-stack-below` turns the row into a column on a window narrower than the breakpoint it
* names (M3's, in px: medium 600, expanded 840, large 1200, extra-large 1600) — M3's "reposition"
* as the window shrinks (§ Layout Breakpoints). A stacked row stretches its children across its
* width unless an `align` was given.

{{-- Children side by side, inside a pane; under one another below a breakpoint.
<x-row gap="space100" justify="end" stack-below="medium"></x-row>
`gap` is a spacing token's name, `space25` `space900` (docs/reference/m3/styles-supplement.md
§ Spacing), and none when left out or unknown. `align` places the children across the row:
`center` (the default), `start`, `end`, `stretch` or `baseline`. `justify` places them along
it: `start` (the default), `center`, `end` or `between`. `wrap` lets them wrap onto more lines.
`stack-below` names a breakpoint `medium` (600px), `expanded` (840), `large` (1200) or
`extra-large` (1600), M3's in px (docs/reference/m3/foundations.md § Layout Breakpoints)
below which the row is a column: M3's "reposition" as the window narrows. A stacked row
stretches its children unless `align` was given.
The row runs in the inline direction, so it mirrors in a right-to-left document by itself. It
takes `as`, `hide-below` and `hide-from` like every layout component, and the caller's `class`
and `style` land on it untouched. Drawn by resources/css/layout/row.css. --}}
