Improve more NTDS attributes

[Schamper]

• Add more typed attributes
• Move some attribute decoding from "global" decoding to class specific
  • The benefit of this is so that we don't fill up ATTRIBUTE_ENCODE_DECODE_MAP with every attribute that requires some additional type tweaking, but keep that logic separated with the classes. The reason for doing additional decoding this way and not in a specific @property def attr_name is so that we also get the better type with .get() and .as_dict().
• Tweak system flags a bit
• Add additional helper methods to NTDS for retrieving certain objects
