RFR: 8279254: PKCS9Attribute SigningTime always encoded in UTFTime [v4]

[Ben Perez]

> Added single-argument `putTime` method to `DerOutputStream` that selects the correct encoding based on the `Date` value. Similarly, a `getTime` method was added to `DerValue` to automatically call the correct decoding function based on the date type specified by the `tag`. Furthermore, the `encode` method in `PKCS9Attribute` was changed to utilize the new `putTime` method.
