Revert of Revert of Change device creation to see the (optional) layer-paint (patchset #1 id:1 of https://codereview.chromium.org/1008863002/)

Reason for revert:
guard in chrome has landed

Original issue's description:
> Revert of Change device creation to see the (optional) layer-paint (patchset #9 id:160001 of https://codereview.chromium.org/988413003/)
>
> Reason for revert:
> need to have chrome opt-in for the older API before this can land (in chrome)

> > Motivation:
> >
> > PDFDevice currently relies on 1) being told that the layer's paint has an imagefilter, and in the case, it creates a rasterdevice. It then relies on (2) canvas itself sniffing the layer's paint and offering to apply-the-imagefilter to call drawSprite instead of drawDevice.
> >
> > This subtle interchange is fragile, and also does not support other unsupported PDF features like colorfilters. This CL is a step toward making this use-raster-instead-of-native approach to layers more completely in the subclass' hands.
