feat(smus): Add domain caching for IdC login

[vpbhargav]

Description
Added a local cache that will list the last 10 recently used domains during login.

The data is stored in the memento storage, which is VSCode's SQLite DB abstraction for storing metadata for extensions.

Motivation
Better UX for login for customers who use multiple domains

Testing Done

Tested locally and also added unit tests
