This adds support to set different permissions to CCCD so security can
be checked when enabling notification which conforms to:
BLUETOOTH CORE SPECIFICATION Version 5.1 | Vol 3, Part G page 2360:
'3.3.3.3 Client Characteristic Configuration
Authentication and authorization may be required by the server to
write the configuration descriptor.'
In addition to that also ensure that notification are not re-enabled
until the proper security level is reached to conform to the following
statement:
'10.3.1.1 Handling of GATT indications and notifications
A client “requests” a server to send indications and notifications
by appropriately configuring the server via a Client Characteristic
Configuration Descriptor. Since the configuration is persistent
across a disconnection and reconnection, security requirements must
be checked against the configuration upon a reconnection before
sending indications or notifications. When a server reconnects to a
client to send an indication or notification for which security is
required, the server shall initiate or request encryption with the
client prior to sending an indication or notification. If the client
does not have an LTK indicating that the client has lost the bond,
enabling encryption will fail.'

This removes the necessity of registering the storage for CCC and make
it part of the declaration itself.

This fixes the coverity problem which which in fact is a non-issue as
the code would assert before reaching that line which makes the NULL
pointer check useless so this removes it.

sizeof(value) returns the size of the pointer, not the pointed string.

This adds initial test for GATT APIs that don't require a connection
thus can be run without any extra setup.
