[css-anchor-position-1] Support safe with anchor-center
https://bugs.webkit.org/show_bug.cgi?id=295503
Reviewed by Elika Etemad.
Make safe keyword work with anchor-aligned element as specified in CSS Anchor
Positioning spec:
https://drafts.csswg.org/css-anchor-position-1/#anchor-center
"When using anchor-center, by default if the anchor is too close to the edge of
the box’s original containing block,
it will "shift" from being purely centered, in order to remain within the
original containing block.
See CSS Box Alignment 3 §4.4 Overflow Alignment:
the safe and unsafe keywords and scroll safety limits for more details."
