We resolve the auto value in IntrinsicForAxis by the ratio determining size
and the preferred aspect ratio. However, this should take
box-sizing into account when using aspect-ratio property.

Based on the spec, if the aspect-ratio property value is:
1) auto: we should always use content-box dimensions.
2) <ratio>: the aspect-ratio works with box sizing dimensions.
3) auto && <ratio>: we use content-box dimensions in all cases.
So we need an extra flag to address that we should use box-sizing or
always use content-box dimensions while computing the size in
ratio-dependent axis.
This also updates some wpts for non-replaced elements because we should
use content-box if aspect-ratio is 'auto && <ratio>'.

We add a new file, AspectRatio.cpp, to definte the method,
ComputeRatioDependentSize. So we don't have to move this function to
WritingModes.h
Besides, we miss the forward declaration of IPC::ParamTraits, so add it
into AspectRatio.h.

We calculate the size of ratio-dependent axis by aspect-ratio while
initializing its ReflowInput, for most of the basic block cases.
This patch doesn't include "Automatic content-based minimum sizes",
which will be handled later. Besides, replaced elements will be handled
later as well.
We don't pass abspos-004.tentative.html because there is still a
spec issue: https://github.com/w3c/csswg-drafts/issues/5151.
For other tests we didn't pass (e.g. block-aspect-ratio-009.tentative.html,
or replaced-element-00x.tentative.html), we fix them later.
Besides, in this patch, we don't handle the case if the size of
ratio-determining axis uses intrinsic size keywords (which needs to be
calculated by its content size). We will fix this in the following bug
(Bug 1646100).

It seems like a reasonable expectation, but it may not hold with massive
ratios. Make it hold by returning the floating point epsilon in that
case.

This restores our previous and per-spec behavior. Comparing only ratios was not
correct in the case one of the dimensions was zero and thus not scaled.
