[UPMLoginDbSunset] Record metrics for the old GMS no passwords dialog

This dialog is shown when a user tries to access the password manager,
but they are on a device with a version of Google Play Services that
is too old for full UPM support. It is also only shown for users who
have either downloaded or didn't have passwords left over in Chrome.

The histogram records the user decision to accept to update or not
in the dialog.
