Revert "Use computed font-size for em/rem resolution."

This reverts commit 41edd5e1.

Bug:1004253

Original change's description:
> Use computed font-size for em/rem resolution.
> 
> This makes us match how Firefox applies minimum font-size and makes us
> not break relative length computation when pages use a font-size less
> than the user's minimum font-size as a basis for widths, heights,
> margins, padding, etc.
> 
> This is a behavioral change for relative lengths for the following
> cases:
> 
> - minimum-font-size does not affect em lengths
> - minimum-logical-font-size does not affect em lengths
> - text autosizing does not affect em lengths
> - text scaling accessibility setting in Chrome for Android does not
>   affect em lengths
> 
> Test expectation changes and reasons:
> 
> Text scaling no longer applies to relative lengths (text zoom set from testRunner):
> 
> svg/zoom/text/zoom-hixie-mixed-008.xml
> svg/zoom/text/zoom-hixie-rendering-model-004.xhtml
> svg/zoom/text/zoom-svg-float-border-padding.xml
> 
> Minimum logical font-size not applying to relative lengths (minimum logical font-size set to
> 9px when running layout tests):
