Support smart shifting for TSComputeRHSJacobianConstant
Since the SNES Jacobian matrices and the TS Jacobian matrices are different, we can safely shift the SNES Jacobians. The TS Jacobian is used only for generating RHS (u'=A*u).

Improve handling of the shift and scale factors in TSComputeRHSJacobian
- TSComputeRHSJacobian does not need to shift or unshift the Jacobian matrix; logically it should be TSComputeIJacobian's resp
Improve handling of the shift and scale factors in TSComputeRHSJacobian
- TSComputeRHSJacobian does not need to shift or unshift the Jacobian matrix; logically it should be TSComputeIJacobian's responsibility.
