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.

d653cac70e More sample count cleanup:
rename getSampleCount -> getRenderTargetSampleCount because it will return
0 when a config is not renderable but *is* supported as a texture format.
(Old name kept around until Chrome stops calling it)

Add virtual GrCaps::maxRenderTargetSampleCount(GrPixelConfig).

Devirtualize isConfigRenderable() and implement as maxRTSC != 0. Separate implementation for version with bool withMSAA param to be removed after Flutter is updated to no longer call.

Consolidate various file static GrSurfaceDesc validators fns into GrCaps::validateSurfaceDesc().
