Ultimately, we want to add support for GDM's new ChoiceList
PAM extension. That extension allows PAM modules to present
a list of choices to the user. Before we can support that
extension, however, we need to have a list control in the
login-screen/unlock screen. This commit adds that control.
For the most part, it's a copy-and-paste of the gdm userlist,
but with less features. It lacks API specific to the users,
lacks the built in timed login indicator, etc. It does feature
a label heading.

At the moment the timed login feature is implemented in the user list.
If there's no user list, we don't show the indicator anywhere and
don't proceed with timed login.
This commit allows timed login to work when the user list is disabled.
It accomplishes this by putting the timed login indicator on the
auth prompt in that scenario.

When we display the hint string for e.g. (or swipe finger), the login
box gets pushed up. This is leftover from older styling and should be
removed. The padding-top is unnecessary and can also be removed, so just
remove the whole line styling login-dialog-message-hint from the
stylesheet.

Allow vertical orientation for the userWidget so that the user-avatar
can be centered and user's name can be placed below it. The plan
for 3.36 is to use this vertical userWidget layout for both lock
and login screen.
The userWidget is also used while creating the user-selection list
at the login, hence we still need to keep the horizontal layout
for userWidget in place.
