Re-evaluate default thresholds for OpenMP and Fusion
What is the expected behavior?
With the recent changes to the gate fusion algorithm and including SIMD we should re-evaluate the default threshold values for enabling OpenMP, and for enabling gate fusion for the different qubitvector based simulations States (Statevector, DensityMatrix, Unitary, Superoperator) to ensure good default performance.
