#14101 Make Fault Distance objects deletable

Enable the standard tree Delete action on RimFaultDistance via
setDeletable( true ). On deletion, remove the generated FAULTDIST result
from the case in the destructor; the object is still attached to the
project tree while the destructor body runs, so the owner case is
reachable.
