Brian Salomon 40242241c3 Revert "Don't key progams/pipelines on origin." 
This reverts commit 943108b0b2.

Reason for revert: clockwise GM bad on android.

Original change's description:
> Don't key progams/pipelines on origin.
>
> SkSL language features that are origin sensitive now use a uniform
> to conditionally flip their result rather than generating different
> code.
>
> Previously we would insert a "rt height" uniform if sk_FragCoord needed
> to be flipped. sk_FragCoord,y was implemented as "realFragCoord.y" or
> "rtHeight - realFragCoord.y" depending on SkSL::ProgramSettings::fFlipY.
>
> Now we instead use a two component vector rtFlip and sk_FragCoord.y is
> always "rtFlip.x + rtFlip.y*realFragCoord.y". We configure rtFlip as
> either (0, 1) or (rtHeight, -1). sk_Clockwise and dFdy simiarly use
> rtFlip.y to emit code that always works with either origin.
>
> Bug: skia:12037
