Add symfony events for more login hooks

[sharidas]

As of now the symfony login events are present in

• https://github.com/owncloud/core/blob/master/lib/private/User/Session.php#L872

There are places like encryption or may be more where we need to have similar events to be added.

GitMate.io thinks the contributors most likely able to help are @PVince81, and @butonic.

Possibly related issues are #31467 (Symfony events added for login failed and public link accessed), #30268 ([WIP] Adding new symfony events to replace old hooks), #31465 (Missing symfony event for failed login attempt), #30996 (Throw symfony events on group actions), and #29174 (Provide symfony event dispatcher events for all older hook types).

The symfony events added for login were for the following methods in https://github.com/owncloud/core/blob/master/lib/private/User/Session.php:

• login() covers the symfony events for loginWithToken() and loginWithPassword().
• loginWithPassword() has before and after symfony events.
• loginWithToken() has before and after symfony events.
• loginWithApache() has before and after symfony events.
• loginUser() has before and after symfony events.

For encryption it is taken care by the post_login event, which happens via postLogin event. Meaning we don't have to do anything there.

I think we have covered the login hooks, due to which this issue was raised.
