feat(dap): implement Restart request (#5651)

Add a restart debug session command, which would issue a
[Restart Request][1], if the debugger supports it and a session is
running. It uses the same arguments and requests used to start the
initial session, when recreating it.

It builds upon #5532, making use of the changes to the termination
workflow of a session.

Closes: #5594
