Discard matchVariant matches with unknown named values (#18799)
This PR fixes two issues:
- When a variant is defined by `matchVariant` it could match unknown
values but not apply the variant (because it's unknown). This would
result in a utility being output that is the _same_ as a bare utility
without variants but a longer name. These were intended to be discarded
but weren't done so correctly.
- Similarly, when we encounter a known value but its not a string the
same thing would happen where we'd output a utility without applying the
variant. This was also intended to be discarded.

Basically given this code:
```js
matchVariant(
  "foo",
  (value) => `&:is([data-foo='${value}'])`,
  {
    values: {
      DEFAULT: "",
      bar: "bar",
      obj: { some: "object" },
    },
  }
)
```

And this HTML:
```html
<div class="foo-bar:bg-none foo-[baz]:bg-none foo-baz:bg-none foo-obj:bg-none"></div>
```

This CSS would be produced:
```css
@layer utilities {
  .foo-bar\:bg-none {
    &:is([data-foo='bar']) {
      background-image: none;
    }
  }
  /* this one shouldn't be here */
  .foo-baz\:bg-none {
    background-image: none;
  }
  /* this one shouldn't be here */
  .foo-obj\:bg-none {
    background-image: none;
  }
  .foo-\[baz\]\:bg-none {
    &:is([data-foo='baz']) {
      background-image: none;
    }
  }
}
```
