[LayoutNG] Allow floats to be placed "before" other floats of the same type.

Floats have some "interesting" behaviour which allows a left (or right)
float to be placed left (or right) of a previous float. This typically
isn't allowed.

This occurs when a float has "negative size" e.g. it has a large
negative margin, which is larger than its width. E.g.
\<div style="width: 50px; margin-left: -150px; float: left;">\</div>

In such cases the float doesn't respect the normal rules, and is
placed in a typically invalid area.

This patch also changes "const LogicalSize& minimum_size" to
"const LayoutUnit minimum_inline_size" for "FindLayoutOpportunity".
