Add AddWatchOnlyWithDB, AddKeyOriginWithDB, AddCScriptWithDB functions

Browse Source 
AddWatchOnlyWithDB, AddKeyOriginWithDB, and AddCScriptWithDB add their
respective data to the wallet using the provided WalletBatch instead
of creating a new WalletBatch object every time. This allows for batching
writes to the database.
