all SV inheriter types have DEBUG_LEAKING_SCALARS data, so always show it

I noticed AV *s in my C debugger didn't the sv_debug_* members, but if I
casted the AV * to a SV * in my C debugger using a expession in my watch
tab, all the info was there. Put the DEBUG_LEAKING_SCALARS in
_SV_HEAD_UNION so the sv_debug_* members appear everywhere (CV/HV/AV/etc),
not just for SVs.
