Revert "alternate approach to unpremul scalePixels()"
This reverts commit c4616804bb407506c6ac1046c7e25e2016911449.
Reason for revert: screwed up the guard I think
Original change's description:
> alternate approach to unpremul scalePixels()
>
> We want to keep the clamps in SkImageShader, and keep unpremul
> scalePixels() happy too.
>
> So we extend SkImageShader's internal API to allow specifying an output
> alpha type, which controls whether we premul or unpremul and how we
> clamp. scalePixels() uses this to draw instead of a drawBitmap() call.
>
> Sort of backwards of usual, we opt our local builds into
> SK_LEGACY_HIGH_QUALITY_SCALING_CLAMP (and Google3 is already defining
> this). Then to rebase Chromium we will _define_ this in Chromium's user
> config, fold it through as if always defined in Skia, then finally
> remove the definition from Chromium's user config.
