Users: Remove deprecated user contact methods.

The three default contact methods (AIM, Yahoo IM, Jabber) were removed for new installations in WordPress 3.6.

This commit removes the remaining references from the codebase, as the associated services were discontinued quite a while ago.

The `user_contactmethods` filter is available for adding or removing contact methods.

Follow-up to [23588], [25606].

Fixes #44374.
