Attachment: Bug 1759816 - Create `EditorDOMPointBase<PT, CT>::ParentPoint()` for avoiding warning spam caused by no necessary checks r=m_kato!

When setting a point, the child must be nsIContent. However, climbing up
the tree from a point with EditorDOMPointBase<PT, CT>, it may reach top of
the DOM tree (fragment). Then, we'd get a warning which wouldn't hit in
usual cases. Therefore, we should add new API to get parent point of an
EditorDOMPointBase<PT, CT> instance and it should check properly before
creating new instance.

Depends on D141195
