This patch breaks FormattingContext::layout_inside() into two functions,
one that creates an independent formatting context (if needed), and
another that calls the former and then performs the inside layout within
the appropriate context.
The main goal here was to make layout_inside() return the independent
formatting context if one was created. This will allow us to defer
certain operations in child contexts until the parent context has
finished formatting the child root box.
Height computation algorithm is actually
different for absolutely positioned boxes
and block formatting contexts (where it doesn't include floats)
Fixes#6408

This commit fixes algorithm for computing auto height (CSS 2.2 10.6.7)
by including floating boxes into computation and implements one of the cases
for computing the height of absolutely positioned, non-replaced elements (10.6.4 rule 3)
