Reason for revert:
Still shows comparable memory regressions.

Original issue's description:
> Activate Complex text on Android after memory improvements
>
> In the blocking bugs of crbug.com/617568 work was done on improving font
> memory managament: Fixing the ref counting of the FontDataCache, zero
> copy access to font blobs and purging the font cache on low memory
> pressure. So it is time to give it another try and see whether this
> addresses the memory regressions observed on bots when activating
> complex text on Android seen in crbug.com/577306.
>
> TBR'ing to get bot results. We will revert again if the regression still
> occurs.
