refactor: auth code (#3525)

    - The overall folder named is now src/auth/ instead of src/credentials/
    - The auth.ts module now focuses only on the Auth client and does not have other related code in the same module
    - When dealing with a Connection object like an Sso, BuilderId, or Credentials/IAM connection, related code was moved from auth.ts to connection.ts. This helps to avoid circular dependencies when working with connections + auth.
    - The functional code previously in auth.ts was moved to src/auth/utils.ts to create separation between the functions and the Auth client.
    - Existing credentials related files were moved in to src/auth/credentials/ to consolidate them
    - A new folder was made in src/auth/ui/ that will hold all auth related UI code, including the status bar item and add connection webview.
