Interface and time loop changes. Processes are in the
next commit.

This is going to replace one part of the local_coupled_solutions
object.

Pass through the interface to avoid the coupled_xs
in the feature.

Pass process_id to FEM::assemble calls.

Drop dt where used together with it's updates etc.

Exemplary on SmallDeformationProcess, storage of dt
is no longer required and the assembly can be repeated
without dependency on the t/dt values.

With this it becomes possible to use the t/dt values
directly instead of storing them in *ProcessData
and retrieving at later point.
