PM-40154: feat: Migrate user data to KeystoreEncryptedSharedPreferences

PM-40154

📔 Objective

This PR creates a new KeystoreEncryptedSharedPreferences that utilizes the AndroidKeystore to encrypt the data stored.

Notable changes:

• This migrates us away from EncryptedSharedPreferences which is deprecated and is not FIPS compliant.
• The keys are not stored as plaintext.
• We currently only support the storing of Strings (this is the only type we need at the moment).

If we had a tech breakdown beforehand, I'd recommend implementing this in the SDK based on our modern encryption primitives instead. Given the stage, I'll comment the minimum to make this reasonably secure. I recommend dropping the separate MAC key, and switching from CBC to GCM. Currently, the API is very easy to misuse, and you generally do not want to expose separate authentication and encryption (without authentication) APIs.
