Remove LayoutListMarker::LocalSelectionRect()

Since we don't paint list marker selection today, the override is
no longer needed(return null Rect as default).

Use NGPhysicalTextFragment::LocalRect for selection painting.

This patch changes NGTextFragmentPainter to use NGPhysicalTextFragment::LocalRect
instead of computing it itself for consistency.

[LayoutNG] Implement LayoutText::LocalSelectionRect.

This patch implements LayoutText::LocalSelectionRect() for LayoutNG.
LayoutText update is straightforward: get paint fragments for LayoutText,
compute selection start/end, compute local rects and unite them.
Since LayoutSelection::ComputeLayoutSelectionStatus was used only for not linebreak
LayoutText, this patch adds workaround for them.

[LayoutNG] Let LayoutText::LocalSelectionRect considering soft linebreak

This patch modifies LocalSelectionRect to consider soft linebreak rect
by unifying rect computing code with NGTextFragmentPainter's.
This patch settles the unified code onto NGPhysicalTextFragment.

This fixes 3 selection failures:
paint/selection/text-selection-drag-in-frame-scrolled.html
paint/selection/text-selection-drag-in-frame.html
paint/selection/text-selection-drag.html
