[lib] creating olm session with device
Summary:
Method to create a session with one peer.
It looks similar but differs from createOlmSessionsWithOwnDevices and trying to duplicate could make the code more complex - additionally createOlmSessionsWithOwnDevices is only for testing and will be removed
Depends on D12130
Test Plan: Call method and test if session creation works, in case of failure error is thrown
