tests: Fix ShadingRateEXTTest.FragmentShadingRatePrimitive The test ShadingRateEXTTest.FragmentShadingRatePrimitive has several errors: 1. The uniform 'u_color' is not set to any value. 2. The test incorrectly assumes GL_SHADING_RATE_1X1_PIXELS_EXT results in the GLSL built-in 'gl_ShadingRateEXT' having a non-zero value. 3. The test attempts to validate the GL_SHADING_RATE_2X2_PIXELS_EXT behavior, but never calls glShadingRateEXT() with this value. 4. kSimplePrimitiveShadingRateGS needs to set gl_PrimitiveShadingRateEXT each iteration of the loop, rather than just once, due to the EmitVertex() call which resets all output variables to undefined values. Once these issues are fixed, the test passes.
