Make sure fixed-length getComputedStyle() inset values roundtrip

Since crrev.com/c/4583533, when we try to get an inset value from an
absolutely positioned box, we always get it from the layout result.

This caused some rounding errors, since layout and CSS values have
different precisions. And this is unexpected to some sites.

This patch makes sure that we directly return result from the computed
style in simple cases (fixed-length values without position fallback
complications), so that the result roundtrips and avoids the rounding
difference.
