[AC-3043] Refactor AuthService to only use organization api key login

[eliykat]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/AC-3043

📔 Objective

AuthService supports multiple login methods via LogInStrategys, including password, SSO, personal api key, etc. This is from old jslib code which was used by multiple clients.

This PR:

1. deletes unused LoginStrategies
2. combines the OrganizationLoginStrategy into the LoginStrategy base class
3. refactors LoginStrategy to remove unused code
4. then combines the LoginStrategy class into AuthService - resulting in a single login method that just does the work itself
5. deletes unused services

The refactoring steps are easier to follow if you review commit-by-commit.

Depends on #621 being merged first.
