fix(linter): avoid no-restricted-globals shadowing false positive

[raashish1601]

Fixes #20807.

Summary

• use the existing IsGlobalReference helper so
  o-restricted-globals checks the current reference instead of any unresolved identifier with the same name
• keep reporting only the unresolved global location access when a later local binding shadows that name in the same file
• add pass/fail coverage for the mixed global-plus-shadowed-local case from the issue report

Testing

• cargo test -p oxc_linter --lib no_restricted_globals
• cargo fmt --all --check

Hey @raashish1601, thanks for your contribution and interest to help! I noticed that #20814 of you is also open. Would you be willing to close that PR as well?
