Revert of Make stencils be attachable to render targets created via SkSurface::MakeFromBackendTextureAsRender… (patchset #5 id:80001 of https://codereview.chromium.org/1924183003/ )

Reason for revert:
Breaking the DEPS roll.

Also seems to be causing failure in DM on some Windows bots:
c:\0\build\slave\workdir\build\skia\tests\surfacetest.cpp:963	kShapeColor == bitmap.getColor(kW / 2, kH / 2)

Original issue's description:
> Make stencils be attachable to render targets created via SkSurface::MakeFromBackendTextureAsRenderTarget
>
> This is a regression from "Refactor to separate backend object lifecycle
> and GpuResource budget decision".
>
> GrGLRenderTarget::CreateWrapped creates only render targets that wrap
> the FBO.
> GrGLRenderTargetTexture::CreateWrapped creates render targets that
> wrap the texture.
>
> Use the latter as the implementation for
> SkSurface::MakeFromBackendTextureAsRenderTarget.
>
> The test contains disabled code. The
> MakeFromBackendTextureAsRenderTarget does not copy the existing texture
> contents to the FBO render buffer.
