Bug 1950067 [wpt PR 50899] - layout: Ignore indefinite stretch on min and max sizing properties, a=testonly

Automatic update from web-platform-tests
layout: Ignore indefinite `stretch` on min and max sizing properties

We were always treating an indefinite `stretch` as the automatic size.
This instead treats it as `0px` on min sizing properties, and as `none`
on max sizing properties, aligning with Blink and this recent CSSWG
resolution: w3c/csswg-drafts#11006
