Remove the singular check for the Jacobian matrix

[sjsprecious]

Current in MICM, we will check whether the Jacobian matrix is singular or not after LuDecomposition (https://github.com/NCAR/micm/blob/main/include/micm/solver/rosenbrock.inl#L251-L252).

Based on my experience, CAM-Chem never did this in practical runs and this check can be costly for GPU runs because a synchronization is needed in order to return the correct value on the GPU (which is not done correctly right now).

Thus it may be easier to remove all the singular check in the MICM CPU & GPU code?
