Remove reliance on AATP Attack Simuation

[ciberesponce]

Right now, DSC pulls down binaries from AATP Attack Simulation repository. This can be overly complex to maintain DSC scripts for no reason--in addition, if anything happens to that external repo, it adversely impacts this repo.

Move what we can to this formal MSFT repo, downloading binaries from the true source as much as possible. Remove binaries that we cannot stage or download from the direct location...
