layout: Only prevent fixed table layout when `inline-size` is `auto` (#35882)

We were ignoring `table-layout: fixed` both for `inline-size: auto` and
`inline-size: max-content`. However, the CSSWG resolved that fixed table
layout should be triggered except when `inline-size` is `auto`.
https://github.com/w3c/csswg-drafts/issues/10937#issuecomment-2669150397

Blink has already adopted this change, and they modified the WPT
`/css/css-tables/fixed-layout-2.html` accordingly. Here I'm doing some
further cosmetic cleanups to the test.
