Remove discard from GrRenderTarget & force it to always go through a RenderTargetContext

Browse Source 
This is a bit sloppy in that it ignores some instances where discards were being issued before.

The creation of the temp RTContext in the RenderTarget's discard method was causing an extra split in the opLists.

This is split out of: https://skia-review.googlesource.com/c/10284/ (Omnibus: Remove GrSurface-derived classes from ops)
