[proposal] Coscheduling move some BeforePreFilter quick check into PreEnqueueExtension

[ZiMengSheng]

What is your proposal: Coscheduling currently checks whether the member Pods of the Gang have reached the Minmember number and whether the Gang has been initialized. K8s 1.28 brings the prequeue extension interface, which can determine whether the conditions for joining the queue are met before the Pod joins ActiveQ. So we can consider putting some Gang checks in PreEnqueue.

Why is this needed:

reduce wasty scheduling cycle.

Is there a suggested solution, if so, please add it:
