GitLab

There are 2 warnings can be displayed on the login screen for the managed
guest session based on the force-install extensions list. Currently the
message is selected based on a static list of white-listed extensions IDs.
This behaviour is extended to decide the warning message based on the
extensions permissions if the extensions ID is not white-listed. The
local state file is updated accordingly, and the default value for the
first time is to display the complete warning message.

The current behaviour for displaying the login screen warnings won't be
switched now to this new behaviour. This will be made in a separate cl.
