Move SecretStorage-related interfaces out to new module (#3244)

* Remove redundant `IAccountDataClient.getAccountData`

This is never called, so we may as well get rid of it

* Move a few more interfaces into `secret-storage.ts`

* Use interfaces from `secret-storage`

* Move IAccountDataClient to secret-storage

* Use `AccountDataClient` from `secret-storage`

* move SECRET_STORAGE_ALGORITHM_V1_AES to secret-storage

* Use `SECRET_STORAGE_ALGORITHM_V1_AES` from `secret-storage`

* Add a test case for the quality gate

* Update src/secret-storage.ts

src/client.ts
