RenderTable::paintBoxDecorations shouldn't do the BackgroundBleedAvoidance optimization if the table collapses borders

paintBoxDecorations is doing the BackgroundBleedAvoidance
optimization if the element's opaque solid rounded borders
obscure border edges.

However, if a table collapses borders, it doesn't paint the
borders. We should use the optimization.
