by moving cond_resched_rcu() to rcupdate_wait.h, we can kill another big
sched.h dependency.

We're trying to get sched.h down to more or less just types only, not
code - rseq can live in its own header.
This helps us kill the dependency on preempt.h in sched.h.

loongarch's signal.c uses rseq_signal_deliver() so it should
pull in the appropriate header to prevent a build error:
../arch/loongarch/kernel/signal.c: In function 'handle_signal':
../arch/loongarch/kernel/signal.c:1034:9: error: implicit declaration of function 'rseq_signal_deliver' [-Werror=implicit-function-declaration]

We don't actually use any timekeeping types, no need to pull in
time64.h.
Also, sched.h uses restart_block; add it as a direct dependency.

thread_info.h pulls in a lot of junk that sched.h that we don't need; in
particular, this helps to kill the printk.h dependency.

More sched.h dependency culling - this lets us kill a rhashtable-types.h

Cutting down on sched.h dependencies: this is going to be used in
workqueue_types.h in the next patch, so we can kill the sched.h
dependency on workqueue.h.

Trimming down sched.h dependencies: timerqueue_types can include just
rbtree_types.h instead of pulling in rbtree.h.

There's really no overlap between uapi/linux/wait.h and linux/wait.h.
There are two files which rely on the uapi file being implcitly included,
so explicitly include it there and remove it from the main header file.

This is needed for killing the sched.h dependency on rcupdate.h, and
pid.h is a better place for this code anyways.

We need to reduce the scope of what's included in sched.h: task_struct
includes a hrtimer, so split out the core types into their own header.

sched.h, which defines task_struct, needs nodemask_t - but sched.h is a
frequently used header and ideally shouldn't be pulling in any more code
that it needs to.
This splits out nodemask_types.h which has the definition sched.h needs,
which will avoid a circular header dependency in the alloc tagging patch
series, and as a bonus should speed up kernel build times.
