If a user can't enable screen saver, they shouldn't be able to
accidentally find screen saver related settings in Settings.
Bug: 260276394
Test: atest ScreenSaverPreferenceControllerTest
Test: manually by settings up a second user on a device that supports
screen saver, switching to that user, and making sure that searches for
"screen saver" don't accidentally reveal settings that can't be
accessed.

This change makes it that the ScreenSaverPreferenceController extends
BasePreferenceController so that it can be readily used and pointed to
from an xml file.

Dreams and docking often refers to "user zero" or "system user".
But more generally, the special user for dreams or switching-to-on-docking
need not be user 0, and in fact won't be in certain modes. So this needs updating.

On devices where non-system users are not allowed to dream, disable the
screen saver setting when the current user is not the system user.
Bug: 213906883
Test: atest ScreenSaverPreferenceControllerTest
Test: Manually with the following steps:
Step 1: On a device with the config setting
config_dreamsOnlyEnabledForSystemUser set to false, make sure that
non-system users can still access the screen saver setting.
Step 2: On a device with the config setting
config_dreamsOnlyEnabledForSystemUser setting is set to true, make sure
that non-system users can not access (or see) the screen saver setting.
Step 3: Make sure that system users can still see the screen saver
setting on a device where config_dreamsOnlyEnabledForSystemUser is set
to true.
