[LayoutNG] Fixepos offset in a nested multicol
When a fixedpos is nested in another OOF inside a nested multicol,
and the outer OOF is not positioned at top:0 inside the containing
block of the fixedpos, the offset of the fixedpos was incorrect. The
reason being that its static position was getting updated in
NGContainerFragmentBuilder::PropagateOOFPositionedInfo() to take the
offset of the OOF into account. This change makes sure that
the static position no longer adds in this offset and instead is
relative to its containing block.Bug: 1198672
