Unify CvDEPTH for formats and subs

As Dave Mitchell pointed out, while putting the CvDEPTH field for for-
mats in the SvCUR slot might save memory for formats, it slows down
sub calls because CvDEPTH is used on subs in very hot code paths.
Checking the SvTYPE to determine which field to use should not be
necessary.
