hooks: update pyqtgraph hook to use Qt bindings selection helper

Update `pyqtgraph` hook to use Qt bindings selection helper, which
should help to automatically exclude extraneous Qt bindings, in
order to prevent multiple Qt bindings from being collected.
The change requires PyInstaller >= 6.5 (and should be no-op with
earlier versions).

Remove the explicit excludes in `pyqtgraph` tests.
