Moved grain_growth_tests from combined to phase_field for #3908
Added gold files for simulations with mesh adaptivity for #3908
Refactored FiniteStrainMultiPlasticity.

There are important, very subtle changes here in addition to the
refactoring that involve the residual2.

Also included more tests of the multi-surface stuff, and
relaxed tolerances in mohr-coulomb tests to get passes on different
architectures.
