Fix the regression bug for ComputeBoids The old implementation missed considering compute program would also enter into applyActiveAttribLocationsMask. However, there was no bindVertexArray before updateAttribEnabled which resulted the previous VAO state was modified in unknown. And that's why ComputeBoids example wouldn't work correctly. This change adds a checking to not enter propagateProgramToVAO if it's a compute program since compute shader doesn't have vertex attributes. And an ASSERT is added to make sure that the right VAO is bound when updateAttribEnabled is called in applyActiveAttribLocationsMask.
