sched/headers: Remove <linux/sched.h> from <linux/sched/topology.h>
...
The <linux/sched/topology.h> file is a self-contained header and users of
it either don't need <linux/sched.h> - or have already included it.
This reduces the size of the header dependency graph.

sched/headers: Move the sched_exec() prototype to <linux/sched/task.h>

sched_exec() better fits into the task lifetime APIs than into the core scheduler

Linux-0.01 already defined 'current' in the middle of sched.h, so this
is an ancient historical precedent - but still in a modern kernel it

Move it further up. If this was done for some obscure dependency
reasons then we'll trigger and document it.
