sched_ext: Move the config-off sub-cap kfunc stubs into sub.c

Browse Source 
The EOPNOTSUPP stubs for the sub-cap kfuncs live in ext.c under #ifndef
CONFIG_EXT_SUB_SCHED while the real definitions live in sub.c. Move the
stubs into sub.c so all sub kfunc definitions live in one file. Pure code
move, no functional change.
