Now that we have a header file for internal scheduler interfaces we can
move some more prototypes into it. By doing that we eliminate the chance
of drivers trying to use something which was not intended to be used.

Helper is for scheduler internal use so lets hide it from DRM drivers
completely.
At the same time we change the method of checking whethere there is
anything in the queue from peeking to looking at the node count.

Idea is to add helpers for peeking and popping jobs from entities with
the goal of decoupling the hidden assumption in the code that queue_node
is the first element in struct drm_sched_job.
That assumption usually comes in the form of:
while ((job = to_drm_sched_job(spsc_queue_pop(&entity->job_queue))))
Which breaks if the queue_node is re-positioned due to_drm_sched_job
being implemented with a container_of.
This also allows us to remove duplicate definitions of to_drm_sched_job.
