[UPMLocalSettings] Move the password check related properties out of safety check model

PasswordsCheckPreferenceProperties is introduced, it includes 2 password check related properties:
- password state
- compromised passwords number
- password check listener

This properties were extracted out of SafetyCheckProperties. This change is needed to implement multiple independent password store checks in follow-up CLs.

P. S. This change is not under the feature flag, but it only replaces
all the occurrences of `SafetyCheckModel.PASSWORD_STATE` with
`PasswordsCheckPreferenceProperties.PASSWORD_STATE` (and the same for 2
more properties).
