model: remove security.py

The security model wasn't implemented and isn't part of the new V3.0
schemata. The (de-)serialization functions weren't used since the
removal of the security attribute from `AssetAdministrationShell` in
1c45c3c.

In turn, also remove security (de-)serialization functions from JSON/XML
adapters.
Remove ABAC XML namespace definition as it isn't used.
