Implement required basic CRUD APIs
- Add session to wallet connect
- Delete session used in tests only
- Get active dApps: the order of retrieval is
based on the first time the DApp was added
in descending order.
Also add tests to validate the main requirements
Closes: #14615
Add new APIs to track if valid pairings are available to be used
by application not to run WalletConnect SDK if not needed.
Closes status-desktop: #12794
