Couldn't only rely on enc fence to decide switching to dpg unpaude mode.
Since a enc thread may not schedule a fence in time during multiple
threads running situation.

v3: 1. Rename enc_submission_cnt to dpg_enc_submission_cnt
    2. Add dpg_enc_submission_cnt check in idle_work_handler

    work schedule

Any jobs which schedule IBs without dependence on gpu scheduler should
use DIRECT pool.

Any jobs schedule direct VM update IBs should use VM pool.

Any other jobs use NORMAL pool.
