Original issue's description:
> Allow stencils to be attached to render targets created via SkSurface::MakeFromBackendTextureAsRenderTarget
>
> This is a regression from "Refactor to separate backend object lifecycle
> and GpuResource budget decision".
>
> GrGLRenderer::canAttemptStencilAttachment was incorrectly returning false
> for all wrapped render targets. This function should return false only if
> the FBO is wrapped (unowned). If the FBO is owned by Skia, we can attach
> stencils.
