This commit re-enables multiple users for all devices. That's possible
as the system image is too large for Android Go nowadays anyway,
therefore no Android Go builds are available anymore.
This commit also increases the maximum number of users from 4 to 5 as
that's what several hardware already overlays set.
This enables links from the settings to the cell broadcast app for
configuring the behavior for received cell broadcasts.
While most hardware overlays already enabled this setting, it's nothing
hardware related, so it makes sense to set here globally for any device.
I'll also open a PR in `vendor_hardware_overlay` to remove the setting
from all overlays there.
