Timeloop: Bind processes

To specify local coupling processes to achieve such a solution scheme, for example, T+M->d->T+M->...

The test case is based on the ThermoMechanicalPhaseField process.

From the second global iteration (where the convergence is evaluated), we will obtain the following solving procedure:

[0] info: [time] Solving process #0 took 0.76743 s in time step #1  coupling iteration #1

[0] info: [time] Solving process #1 took 1.17067 s in time step #1  coupling iteration #1

[0] info: [time] Solving process #2 took 0.068895 s in time step #1  coupling iteration #1

[0] info: [time] Solving process #0 took 0.517937 s in time step #1  coupling iteration #2

[0] info: [time] Solving process #1 took 1.27277 s in time step #1  coupling iteration #2

[0] info: [time] Solving process #0 took 0.192399 s in time step #1  coupling iteration #3

[0] info: [time] Solving process #1 took 0.556535 s in time step #1  coupling iteration #3

...

[0] info: [time] Solving process #0 took 0.262382 s in time step #1  coupling iteration #21

[0] info: [time] Solving process #1 took 0.560019 s in time step #1  coupling iteration #21

[0] info: [time] Solving process #2 took 0.028058 s in time step #1  coupling iteration #21

Converged.

This implementation enables a local fix-stress split solution of the hydro-mechanical coupling problem within three or more processes, for example H+M ->Phasefield .

This is a prepositive development for the THMPhaseField process (MR: !4608 (closed)).
