Removing unnecessary location::nearby::CredentialStorage class.

This class was only kept to satisfy MockClass requirements for cl/472776321.
The location::nearby::api::CredentialStorage class located under
platform/implementation/credential_storage.h contains virtual functions which
satisfy the same requirements. This CL will remove excess code.
