[GeoMechanicsApplication] Extend the Check member function of the TransientPwLineElement

[rfaasse]

As a developer, I want to make sure the TransientPwLineElement performs the expected checks, also for 2D/3D.

Acceptance Criteria

• The line element carries out the same checks as for 1D elements
• For 2D/3D The line element performs the correct checks, see TransientPwElement for reference.

Note: This does not include the checks on the materials that are done right now, they should be moved to the respective constitutive law

Refinement 13/01/2025

Checks that are for the constitutive law should remain there. Here we check the kind of constitutive law and variables (water pressure, DT_water_pressure, volume_acceleration, DOFs, etc).
