Attachment: Bug 1727479 - Make `WhiteSpaceVisibilityKeeper::PrepareToSplitAcrossBlocks()` adjust split point if it's in non-splittable node r=m_kato!

Selection can be collapsed in a non-splittable element like a void element
and data nodes such as a comment node. In this case, we should split the
parent block at before the void element (Blink almost does so, except
<embed>, <hr> and <wbr>).
