sched: Add support to pick functions to take rf

Some pick functions like the internal pick_next_task_fair() already take
rf but some others dont. We need this for scx's server pick function.
Prepare for this by having pick functions accept it.

[peterz: - added RETRY_TASK handling
         - removed pick_next_task_fair indirection]
