[CI/UT][Refactor] move e2e spec decode and deepseek acc test to per pr (#1136)

### What this PR does / why we need it?
1. run deepseek acc ut per pr --- multicard CI time increased by 9 min
2. run spec decode e2e test on v1 per pr --- singlecard CI time
increased by 3 min (partly is disabled due to not work now)
~~3. align the output of whether dbo is enabled or not~~
    The generated results with and without dbo cannot be aligned.

4. skip V0 mtp test due to failure in

5. fix some version conflicts

CI passed with new added test.
