ANDROID: Sched: Add restricted vendor hook in wake_up_new_task()

Browse Source 
Our vendor logic classifies task as a major task and CPU resources
are preferentially allocated for improving performance.

Added a hook in wake_up_new_task for task classification before
moving to the runqueue

This vendor hook was part of
commit 292f430816
(ANDROID: Sched: Add restricted vendor hooks for scheduler)

But commit 7219ca326a
(Revert "ANDROID: Sched: Add restricted vendor hooks for scheduler")
deleted above vendor hooks stating unused

Adding back above vendor hooks required for EMS.

Bug: 259900798
