Revert of Respect declared font style on Android.

Revert of Respect declared font style on Android. (patchset #6 id:100001 of https://codereview.chromium.org/1092093002/)

Reason for revert:
Failed on the compile bots.

Original issue's description:
> Respect declared font style on Android.
> 
> Previously the normal/italic style bit was obtained from scanning the
> font file. With the new format the style may be stated explicitly, and
> this explicit value in the configuration file should override any
> information obtained from the font data itself.
> 
> This change allows the font element's style attribute to override the
> font's style, but retains the default 'auto' setting for backwards
> compatibility. Repecting the style bit may become more important with
> variation fonts, because it will be up to the configuration writer to
> determine what values of the 'slnt' variation should be considered
> 'normal' or 'italic'.
