This reverts commit 174c8fdaa25c49ca36b702598f3fc08f72cc4f29.

Reason for revert: see https://github.com/w3c/csswg-drafts/issues/6071#issuecomment-801338121

Original change's description:

[AspectRatio] Fix flex-aspect-ratio-026.html in legacy

Implement min/max size transfers for replaced elements:
https://drafts.csswg.org/css-sizing-4/#aspect-ratio-size-transfers

Mark both flex-aspect-ratio-025.html and flex-aspect-ratio-026.html as
passing for legacy and update these tests to take both main and cross
size padding into account.

Add flex-aspect-ratio-027.html to verify that min/max-size transfer does not always happen just because aspect-ratio is present.
