LCM: work on a elasto-viscoplastic model

Isotropic hardening, isotropic yield condition
LCM: more work on elastoviscoplastic

Sorting out the embedded evaluation types and the local nonlinear solve.

Note that there seems to be some difficulty combing operations with an
Intrepid::norm(Intrepid::Tensor<>) object. I found a work around, but I need
to talk to Mota to see if this is expected behavior.
LCM: Finish up ElastoViscoplastic model, ready for testing

I am going to push this today, tests are still in development.
