Improve `CTIHelper` and its methods

[buixor]

What would you like to be added?

We currently expose a CTIHelper expr method, but it has a few shortcoming:

1. We might make its usage easier than currently (ie. we need to do CTIHelper(evt.Overflow.GetSources()[0]) or something similar.
2. We are exposing only a few properties via helpers
3. The SmokeItem isn't up-to-date (ie. no mitre techniques)
4. We lack "convenience" helpers

Why is this needed?

make cti helpers great again
