This returns a partial module morphism from a free module with basis to an ambient free module, indexed according to the support order.

Calling the morphism is like calling the element method IndexedFreeModuleElement._vector_, but it would also work with elements of infinite-dimensional modules because an appropriate finite-dimensional submodule will be used.

This generalizes the interaction of _dense_free_module, get_order, and _vector_ in CubicHeckeAlgebra; and it makes the morphism used by _vector_ explicit.

Also for ModulesWithBasis.FiniteDimensional we can generalize the following methods of FreeModule_generic (from sage.modules):
coordinates, coordinate_vector, coordinate_module.

Depends on #33431
