Add InputStylesheetsTest, the inputs twin of the actions stylesheet test

Plan step 36, step 0 of the inputs stream: mirrors ActionStylesheetsTest's
five checks over the seventeen inputs components already rewritten, plus
pagination (its four views live under resources/views/pagination/**, not
components/, so it gets its own small versions of the two view-reading
checks). The "no class list" check also recognises the wrapper fields'
`:class="$attributes->get('class')"` (Blade's own prop-forwarding syntax,
the only way a component with no root element of its own hands the caller's
class to its field) and a `'class' => '…'` attribute-bag entry, and exempts
field.css's week-long autofill transition from the motion-token check.

The new test caught three already-rewritten components writing a bare
`md-visually-hidden` class, which a package view no longer does (only the
three interaction classes, or the caller's own class, reach a view): field's
character-count live region, search's result-count live region, and chip's
native checkbox under a bound filter chip. Fixed by giving each its own
data-md-* hook with the same visually-hidden declarations in its stylesheet,
and chip.css was also missing its `tooltip.css` import for the tooltip
chip.blade.php renders.
