This also removes the TABLE_ATTRS_DIRTY optimization. Constructing nsMappedAttributes isn't really expensive and we do it all the time anyway.

This has multiple benefits:
- It makes DLBI detection of background-position changes work for buttons.
- It makes background-attachment: fixed work for button backgrounds.
- It allows the willPaintBorder optimization to be used for button background
drawing, which reduces the background clip to not overlap with opaque borders.
The willPaintBorder optimization requires a change to the reftest 611574-2.html.
This reftest compares backgrounds to inset box shadows. Box shadows those don't
have a willPaintBorder optimization, so we'd get different results due to the
borders - inset box shadows will bleed through the rounded corner anti-aliasing
of the border, backgrounds won't any more. So we just turn off button borders
and cover the outer edges of the borders with an outline in that reftest.
