Bug 1789255: Anonymous children of elements with content-visibility should not be skipped for layout r=emilio
Some anonymous children are important for properly sizing their parents
even when those parents hide content with `content-visibility`. This is
shown by regressions in the proper layout of some form elements with
`content-visibility`.
This change introduces a more conservative approach for avoiding layout
of hidden content. Instead of leaving all children dirty during reflow,
reflow anonymous frames (and nsComboboxDisplayFrame, a specialized kind
of anonymous frame). This change means that frames may only lay out some
of their children, so it must introduce some more changes to assumptions
during line layout.
In addition, this change renames `content-visibility` related methods in
nsIFrame in order to make it more obvious what they do.
