[PE] Ensure invalidation of table section when any table col is replaced 

Table section paints table col's background on its display item, so when
table col's background changes, we invalidate all table sections.
See https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/paint/table_paint_invalidator.cc?rcl=597a899086d4baebb543eb55b7bd283a3b2068a1&l=43

Now let LayoutObject::BackgroundChangedSinceLastPaintInvalidation() be
initially true, so that a new col will be treated as background changed.
