MixingLength-based turbulent viscosity is not correct in RZ #32112
Description
Bug Description
We need to add the hoop strain to the tensor norm while computing the viscosity.
This is fine in the kernels, but the functor material wants to evaluate the hoop strain on the axis for symmetry BCs which is a zero division. We need to use the functor material in the Newton solve.
Should cause differences on the order of 1%.
Steps to Reproduce
The implementation is wrong so every Mixing length run in RZ will reproduce it.
Impact
Incorrect results for RZ with mixing length.
