Closes#18458.
Matches other browsers in test-cases like:
<div id="t" style="border-top-left-radius: 5px 5px"></div>
<script>alert(t.style.borderTopLeftRadius)</script>
(I think it'd be nicer to preserve the original value completely, but not going
to complain given we already do this for all sorts of Rect<T>s and such, and
this is much easier).
We enter the Custom(..) code path from other random places, like to remove the
relative lengths from a calc expression while zooming, or whatever craziness
MathML font-size uses, and we don't want to set the dependency on those cases.

This avoids grabbing the document when values that inherit from the body,
whatever that means, aren't under the body.
In that case we'll get a semi-random value, but that's also mishandled by Gecko
anyways (and probably Blink, though haven't tested), and doesn't really make
much sense.

Measure PropertyDeclaration more thoroughly.
This patch replaces the handwritten MallocSizeOf implementation for
PropertyDeclaration with a derived one, which gives much more thorough
measurement.
This requires (a) deriving MallocSizeOf for a *lot* of additional types (most
of which already have `derive(HeapSizeOf)` in Servo builds), and (b)
implementing MallocSizeOf for a few more types in the `malloc_size_of` crate.
These changes would significantly improve the reporting coverage for gmail if
it weren't for the fact that SpecifiedUrl isn't measured due to a lack of
clarity about its fields; that can be fixed as a follow-up once bug 1397971 has
landed.

Sometimes, we want to use extremely small pixel value in transform, e.g.
translate(calc(0.001px)), which should be rendered correctly together
with scale(100000). This patch only fixes this case for Servo because
Stylo still uses Au on the Gecko side, even if we pass pixel value into
FFI directly in the previous patch.
We replace Au with CSSPixelLength for the length part of
computed::CalcLengthOrPercentage. Therefore, it would be easier to use
CSSPixelLength for all other LengthOrPercentage{*} types.
First, we define computed::CSSPixelLength which contains a CSSFloat, a
pixel value, and then we replace computed::Length with CSSPixelLength.
Therefore, the |ComputedValue| of NoCalcLength, AbsoluteLength,
FontRelativeLength, ViewportPercentageLength, CharacterWidth, and
PhysicalLength is CSSPixelLength.
Besides, we drop NonNegativeAu, and replace computed::NonNegativeLength
with NonNegative<computed::Length>. (i.e. NonNegative<CSSPixelLength>)
stylo: Add support for calcs in base size calculation
This tracks an offset along with the ratio for the keyword font size data.
The offset gets used when a calc is involved whilst inheriting font-size
(it is the computed value of that calc ignoring em/percentage portions,
which go into the ratio). If the family or language changes, the new font
size can be computed by taking the keyword's size in the context of that
family/language, multiplying it by the ratio, and adding the offset.
