This reverts commit ad9d774c1f.
Reason for revert: Task Test-Debian10-Clang-NUC7i5BNK-GPU-IntelIris640-x86_64-Release-All-DDL3_TSAN has been failing since this CL landed.
Original change's description:
> Add public API support for SkImageFilters::RuntimeShader
>
> This new image filter constructor enables SkRuntimeEffects to be
> used as shaders within the ImageFilter DAG. The shader is created
> lazily using the SkRuntimeShaderBuilder enabling the resulting
> shader to consume the previous stage of the ImageFilter graph.
