layout: Restrict stretch alignment to flex items with computed auto size (#36288)
We were allowing `align-self: stretch` to stretch flex items whose cross
size behaves as `auto`, including cyclic percentages.

However, https://github.com/w3c/csswg-drafts/issues/4525 resolved that
stretching should only happen when the cross size computes to `auto`.

So this patch exposes this information in `ContentBoxSizesAndPBM`, and
refactors the flexbox stretching logic.

Fixes: #36285

Testing:
 - `/css/css-flexbox/quirks-auto-block-size-with-percentage-item.html`
 - `/css/css-flexbox/stretch-requires-computed-auto-size.html`
