[TransformInterop] Make preserve-3d still be no-op on inlines.

Make transform-style: preserve-3d still be a no-op on non-replaced
inline elements rather than making it force a stacking context and a
containing block.

This matches Gecko's behavior, and I think the intent of the spec change
that this is implementing. The proposal to change the spec to match is
in https://github.com/w3c/csswg-drafts/issues/6430 .

This change also means we can avoid worrying about fixing the DCHECK()
failures triggered by having an additional way of making non-replaced
inlines be a containing block for fixed-positioned elements.
