[PM-24745] Decrypt ciphers using decryptManyWithFailures from SDK (#16190)

* Add SDK call to decryptManyWithFailures instead of decryptMany

* Move logic back to decryptCiphersWithSdk

* Fix return type of decryptCiphersWithSdk

* Add unit tests for decryptCiphers()

* Add unit tests for decryptManyWithFailures

* Filter out undefined objects from failedCiphers

* Update name for failed-decryption ciphers

* Fix type checking errors in tests

* Fix tests with new changes from main

* Migrate decryptMany call to use decryptManyWithFailures

* Remove deprecated decryptMany function, along with all calls ot the function
