Changes since 1.18: +2 -12 lines

-clean up the interface to uvm_fault: the "fault type" didn't serve
 any purpose (done by a macro, so we don't save any cycles for now)
-kill vm_fault_t; it is not needed for real faults, and for simulated
 faults (wiring) it can be replaced by UVM internal flags
-remove <uvm/uvm_fault.h> from uvm_extern.h again
