Bug 1789255 forced the reflow of all anonymous in-flow children of content-visibility: hidden elements. In some cases that can lead to more reflows than necessary, because this work-around is really only useful for anonymous blocks. In some cases, particularly involving content-visibility on the <body> element, this can lead to a decent number of reflows. This change tracks narrowing the work-around to only include anonymous blocks.

Reflow fewer types of anonymous children (only anonymous blocks) of
content-visibility: hidden elements. This reduces the number of
reflows for skipped content. This also adjusts to the implementation of
IsHiddenByContentVisibilityOnAnyAncestor() to match the implementation of
IsHiddenByContentVisibilityOfInFlowParentForLayout() in only skipping
one layer of anonymous content.
