[line-clamp] Hide from paint non-fixed-height abspos after clamp
With the continue: collapse variant of line-clamp, absolutely
positioned boxes that are after the clamp point in the layout tree
should be hidden from paint. However, abspos with an indefinite block
size were not always being hidden.
The reason for this was that for such abspos,
OutOfFlowLayoutPart::CalculateOffset performs an initial layout,
which can end up becoming the final layout of the abspos, which does
not happen for the fixed-height abspos that we had tested previously.
As it turns out, that layout was not checking the NodeInfo's
is_hidden_for_paint field to determine whether to hide the fragment.
This change fixes that.
