Bug 1679672 [wpt PR 26668] - [css-flex] Fix LayoutUnit overflow in automatic minimum size calculation, a=testonly

Automatic update from web-platform-tests
[css-flex] Fix LayoutUnit overflow in automatic minimum size calculation

When using the aspect ratio, we were doing
size = large1 * large2 / large3.
large1 * large2 was overflowing LayoutUnit.

Now we do those calculations with the operands as doubles. We still
multiply first because *most* of the time these values will all be
integers, and all the integers up to LayoutUnit::Max()*LayoutUnit::Max()
can be exactly represented with double precision.
