Bug 1727434 - Replace GetCrossDocParentFrame nsIFrame::IsVisibleConsideringAncestors with GetCrossDocParentFrameInProcess. r=tnikkel

Browse Source 
IsVisibleConsideringAncestors has a PresShell::IsUnderHiddenEmbedderElement which
is representing ancestor's visibility state in different process (but only for
contents processes). so it doesn't need to walk up the frame tree across process
boundaries.
