Remove remaining template template parameters

[mattldawson]

Remove any remaining template<template<class> class MatrixPolicy> arguments in favor of using just template<class MatrixPolicy>. The remaining instances of these arguments appear to be only on the RosenbrockSolver, sub-classes of RosenbrockSolver, and tests/examples of RosenbrockSolver.

Acceptance Criteria

• The MICM repo no longer has any template<class> class

Ideas

• If the type of the MatrixPolicy is needed, the IntMatrix and value_type might be useful: https://github.com/NCAR/micm/blob/ee5c03e904d9dc3d60619dc9dbce06232bd32852/include/micm/util/matrix.hpp#L32-L34
