[css-flex] Obey stretch size in replaced items' content size suggestion

Content size suggestion is just min-content size. The min-content size
of a replaced element is supposed to account for preferred size in the
opposite axis. We were not doing that for content size suggestion when
the opposize axis preferred size came from a flexbox's fixed cross size.

In the example below, Blink now gives the image content size suggestion
100px because 100 = 300*150/50. Before this patch Blink gave it a
content size suggestion equal to its natural width 300px.

<div style="display: flex; height: 50px;">
  <img src="support/300x150-green.png">
</div>

Firefox matches Blink's behavior before this patch. We may have compat
issues.

See https://github.com/w3c/csswg-drafts/issues/6693 for discussion of
this new behavior.
