Brian Salomon 2a4f983c94 Remove GrSurfaceOrigin from GrSurfaceDesc. 
This field has no interpretation at the GrTexture/GrGpu as the orientation is
handled at the GrSurfaceProxy level.

This change requires GrGpu to accept a GrSurfaceOrigin when creating a texture with initial data. The origin refers to the texel data to be uploaded. Longer term the plan is to remove this and require the data to be kTopLeft. Additionally, kBottomLeft will only be allowed for wrapped texture/RTs as this evolves.
