Minor table painting optimizations

Reviewed by Alan Baradlay.
Remove the `setHasVisibleBoxDecorations(true()` from
`RenderTableCell::styleDidChange()`.
This dates from the khtml days, and I don't believe it's necessary.
`RenderBlock::paintObject()`
checks `hasVisibleBoxDecorations` before calling `paintBoxDecorations()`, and
`RenderTableCell::paintBoxDecorations()` only paints the box decorations for
the cell, not for
the section, row, colgroup or col, so the check appears to be valid.
* Source/WebCore/rendering/RenderTableCell.cpp:
(WebCore::RenderTableCell::styleDidChange):
* Source/WebCore/rendering/RenderTableRow.cpp:
(WebCore::RenderTableRow::paintOutlineForRowIfNeeded): We only need to compute
`adjustedPaintOffset` if calling `paintOutline`.
* Source/WebCore/rendering/RenderTableSection.cpp:
(WebCore::RenderTableSection::paintObject): Check `hasOutline()` before calling
`row->paintOutlineForRowIfNeeded()`.
