Don't transfer indefinite height: stretch to inline axis (#34557)

Browse source 
Consider this testcase:
```html
<canvas style="aspect-ratio: 1; height: stretch; background: cyan"
        width="200" height="100"></canvas>
```

To compute the intrinsic inline sizes we were treating `height: stretch`
as the natural height (100px) and then transferring that to the inline
axis through the preferred aspect ratio. So the element was 100px wide.

However, an indefinite `stretch` should be treated as an automatic size,
which wouldn't be transferred to the inline axis.

The fix actually makes the code slightly simpler.
