Use JCA names for block modes, paddings, and digests.

This replaces int-based enums from KeyStoreKeyConstraints with
String values commonly used in JCA API.

As part of under the hood refactoring:
* KeyStoreKeyCharacteristics and KeyStoreKeyConstraints have been
  merged into KeyStoreKeyProperties.
* KeymasterUtils methods operating on KeymasterArguments and
  KeymasterCharacteristics have been moved to their respective
  classes.
