[Pass] Refactor use-def chain analysis

[chhzh123]

Description

This PR refactors the use-def chain analysis to better figure out the equivalent variables in a program with deep nested functions.

1. Remove the original use-def pass before type annotation to reduce the maintenance burden.
2. Add a new analyze_use_def pass in passes.py, which leverages the union-find structure to get the equivalent tensors.
