Re-land skips ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11 to pass
the bots. In fact, ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11 is
not a regression. The reverted CL added more SSBO features and triggered the
failure. To enable ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11,
we should support SSBO in render pipeline. This needs to bind SSBO to UAV
registers in link time instead of compile time since output variables also
occupies the UAVs. Let's enable this test when we support SSBO in render
pipeline. Currently, we shouldn't block the SSBO implementation in some common
features.
