[CI] Enable vllm tests (#5130)

Enabled initial vllm tests, tests came from jira issues.

Part of
#3899

Additionally redesigned liger tests to be similar to SGLang.

I will add coverage reports in the next PR

- [x] Need to rename workflow yml file before the merge. Will keep old
name for testing for now.
