Joda-Time to Java time: Add support for Method Parameter Migration

[amishra-u]

What's changed?

• Added support for safe migration of method parameters.
• A method parameter is considered safe for migration if:
  • All expressions referencing the parameter within the method body can be migrated.
  • All arguments assigned to this parameter in method calls can be migrated.

Key Changes:

1. Used data flow analysis to identify the referencing expressions for method parameter.
2. Added VarTable to track all method parameters across files.
3. Added new test cases and updated existing ones to reflect the changes.

Not Implemented Yet:

1. Migration of method return statements.
2. Migration of class variables.

Checklist

• I've added unit tests to cover both positive and negative cases
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files
