FRP: save password quality in DPM.resetPassword

When setting a password from DPM.resetPassword(), the actual quality of the
password was not passed to LockSettingsService (instead, the minimum required
quality was passed which is often UNSPECIFIED). As a result, during FRP we
would see inconsistent state and skip it.

Bug: 110172241
Test: Set credential via DPM.resetPassword(), factory reset device to trigger FRP, verify FRP shows.
