Fix changing state of keys and key items to respect key state model

[lubomirw]

Changing key state should respect key state model which is not working now. For example, it is possible to destroy private key (key item) and then use operation compromise (key) to set private key back to compromise state since that operation is applied without check on all items

• check if key state change is valid when making it on key (key item), applied to all key items. Such an operation should be applied only to key items where it is valid state transition
• same is valid for enable/disable operation on whole key. Now it throws exception if you try to enable key and one of key items is already enabled
• check if key state change behave correctly also for bulk operations
• consolidate messages in event history for changing key state: Key is already DESTROYED and Key is already destroyed. Label of KeyState enum can be used.
• rename KeyState enum COMPROMISED_DESTROYED to DESTROYED_COMPROMISED (also label and code)
• add check before cryptographic operations in CryptographicOperationService if key used is enabled and in state Active
