Fault Reactivation: Add more materials

[kriben]

• Add xml file with four default materials:
  • Overburden:
    • youngs modulus: 2 gigapascal
    • poisson number: 0.3 (unitless)
    • density: 2000 kg/m3
  • Sand:
    • youngs modulus: 5 gigapascal
    • poisson number: 0.3 (unitless)
    • density: 2000 kg/m3
  • Intrareservoir Shale:
    • youngs modulus: 5 gigapascal
    • poisson number: 0.25 (unitless)
    • density: 2000 kg/m3
  • Underburden:
    • youngs modulus: 20 gigapascal
    • poisson number: 0.2 (unitless)
    • density: 2000 kg/m3
• Export materials to INP file.
• Export node+element sets with overburden, sand, intrareservoir shale, underburden (see Fault Reactivation updates #10677)
