Closes #754

When I tried inference with TP, I got a message like:

ValueError: Ray is not installed. Please install Ray to use distributed serving.

although I've already installed Ray.

This turned out be due to the following error in importing Ray data:

 File "/home/wskwon/anaconda3/envs/test-ray/lib/python3.9/site-packages/ray/air/__init__.py", line 2, in <module>
    from ray.air.config import (
  File "/home/wskwon/anaconda3/envs/test-ray/lib/python3.9/site-packages/ray/air/config.py", line 25, in <module>
    from ray.data.preprocessor import Preprocessor
  File "/home/wskwon/anaconda3/envs/test-ray/lib/python3.9/site-packages/ray/data/__init__.py", line 3, in <module>
    import pandas  # noqa
ModuleNotFoundError: No module named 'pandas'

The make_attn_bias in hpu_model_runner doesn't cover the non-causal
embedding model mask set and also vertical mask off is not set when
merged prefill is enabled.
