reenable ImageFilter.shader equality checks consider uniform values test #180762
Description
#180759 found that ImageFilter.shader equality checks consider uniform values is disabled in fragment_shader_tests.dart. I tried to enable it and it has since atrophied. We need to get it reenabled.
failure:

Expected: _FragmentShaderImageFilter:<ImageFilter.shader(Shader#644956568)>
