Implement the from-font value for font-size-adjust

The 'from-font' value is newly added to CSS Font Module Level 5 [1],
which allows the browser to automatically determine a font-size-adjust
value based on the primary font. This change implements it.

[1] https://www.w3.org/TR/css-fonts-5/#valdef-font-size-adjust-from-font

We tweak font-size-adjust-013.html to make Windows happy. The platform
got a one-pixel mismatch of width and height due to subpixel rendering.

Test:
