[perflint] Ignore rule if target is global or nonlocal (PERF401) (#19539)

## Summary

Resolves #19531

I've implemented a check to determine whether the for_stmt target is
declared as global or nonlocal. I believe we should skip the rule in all
such cases, since variables declared this way are intended for use
outside the loop scope, making value changes expected behavior.

## Test Plan

Added two test cases for global and nonlocal variable to snapshot.
