Refactor oobe/login screens so lock screen can be loaded faster.

chrome/browser/resources/chromeos/login/login_shared.html

+<!--
+This file is included for OOBE, login, and the lock screen. Only files which are
+needed by all three scenarios should be included here. If a file should only be
+shared between OOBE and login, add it to login_login_oobe_shared.html.
+
+Any additional include increases the lock screen initialization time.
