[nemo-systemsettings] Add UserInfo. Contributes to JB#49173

Implement UserInfo class that displays user information. Default
constructor creates user for currently logged in user. UserInfo doesn't
update automatically by itself but the data is shared between instances
and thus updating one instance of the same user will change the others.
