incorrect `-Wunused-imports` when module exports multiple records with the same accessor names
## Summary
GHC emits unused imports warnings when the module that is imported from has `DuplicatRecordFields` activated and exports Records with same acessor fields
## Steps to reproduce
```hs
{-# LANGUAGE DuplicateRecordFields #-}
module A where
data R = MkR {ra :: Int, rb :: Bool}
data R' = MkR' {ra :: Int, rb :: Bool}
```
```hs
{-# LANGUAGE OverloadedRecordDot #-}
{-# OPTIONS_GHC -Wall #-}
module B where
import A (R (ra), rb) -- this line emits the warnings for `rb`
x :: R -> Bool
x a = a.rb
y :: R -> Int
y a = a.ra
```
## Expected behavior
No unused import warning
## Environment
* GHC version used: ghc 9.6.2
Optional:
* Operating System: NixOS 23.11
* System Architecture: x86_64-linux
