[FluidDynamicsHydraulicsApplication] Adding new hydraulic utilities; inflow detection and artificial viscosity.

[uxuech]

📝 Description
"In this PR, we add two new methods to the hydraulic utilities:

• Moving the artificial viscosity calculation from the hydraulic solver to this utility to improve computational cost.
• Avoiding inflow into the domain. In the future, new outlet processes will be added, and there is an option where we prevent fluid from entering the domain, allowing only tangential movement to the normal of the model part where the outlet condition is applied.

Reminder for the future: The test for the artificial viscosity calculation is performed in the test of the TwoFluidNavierStokesFractional element within the Calculate method, where the artificial viscosity is actually computed.
Its application in Python is tested in the solver test. Therefore, adding an extra test to evaluate the method itself within the utility is not considered necessary."

• Export the methods to Python to enable their use in the outlet processes.
• Test the new utilities
