Make callCbs() public.

Browse Source 
VerilatedVpi::callCbs() can be used by the user to signal
simulation-related callbacks, e.g.
VerilatedVpi::callCbs(cbStartOfSimulation).

The information if any callbacks have been called may be important to
drive an evaluation until no further changes are observed.
