Handling RISCV-DV program termination

[mkurc-ant]

This PR adds proper handling of RISCV-DV program termination reported by a running program to the simulation. The intention is to make the simulation stop once the program finishes to speed up CI runs. This is done via parametrization of VeeR mailbox address used for communication between them and injection of the proper address as used by RISCV-DV programs.
