sched_ext: Move sources under kernel/sched/ext/
The sched_ext sources had grown to ten ext* files directly under
kernel/sched/. Move them into a new kernel/sched/ext/ subdirectory and drop
the now-redundant ext_ prefix. ext.c/h keep their names.
kernel/sched/ext.{c,h} -> kernel/sched/ext/ext.{c,h}
kernel/sched/ext_internal.h -> kernel/sched/ext/internal.h
kernel/sched/ext_types.h -> kernel/sched/ext/types.h
kernel/sched/ext_idle.{c,h} -> kernel/sched/ext/idle.{c,h}
kernel/sched/ext_cid.{c,h} -> kernel/sched/ext/cid.{c,h}
kernel/sched/ext_arena.{c,h} -> kernel/sched/ext/arena.{c,h}
The include paths in build_policy.c and sched.h, the MAINTAINERS glob, and a
few documentation and comment references are updated to match. No code or
symbol changes.
