Andreas Kling 20c859519b LibWeb: Support cellpadding=0 and invalidate table cells when it changes
We were incorrectly treating cellpadding=0 as if the attribute was
missing. This commit fixes it so it behaves as `padding: 0` on cells.

When adding a test, I discovered that we were not invalidating style for
cells when their containing table's cellpadding attribute changed.
So this commit fixes that as well.
