[xh]Optimize prompt for block params generation in HuggingFace

[matrixstone]

Description

For the task to generate different block params: block_type, pipeline_type, action_code, etc based on block description,
this PR optimizes it by split one prompt to multiple small prompt for individual prompt and run them in parallel.
Since hugging face charge LLM instance by time not number of request, this change does not affect money spending.

However because we can tailer and focus on prompt for each different param, I got 100% correctness with 10 examples I tried: https://docs.google.com/spreadsheets/d/1-fongvJv0lrtNp06wbnDqxmPNp66lCBJ-8TVKuftDds/edit#gid=0
Previously it is 70%.

How Has This Been Tested?

1. Tested with commands. Result recorded in https://docs.google.com/spreadsheets/d/1-fongvJv0lrtNp06wbnDqxmPNp66lCBJ-8TVKuftDds/edit#gid=0
2. Tested with Mage UI. Screenshot:
