[IOT-2247] [IOT-2308] Clean up provisioning/sample/*.json files

The goal is to make the .json more readable an remove confusing extra
values.

I tried to leave them functionally identical, with
the exception that I merged the /doxm (Read, Update) and /roles
(Full Control) ACEs into a single ACE with permission 14
(Read, Update, Delete) which is sufficient for both /doxm and /roles.

I verified that at least JustWorks and Random PIN files work,
as well as security unittests.
