[CI] Add CI case for MTP accept ratio (#5570)

* Implement test for MTP accept ratio

Add test for MTP accept ratio with assertions on results and metrics.

* Update test_ernie_21b_mtp.py

* Refactor test_mtp_accept_ratio for baseline comparison

Refactor test_mtp_accept_ratio to compare results against baseline file and metrics.

* Fix formatting issues in test_ernie_21b_mtp.py
