Make folders for Cosmos Gen3

[zarlo]

To make it less work to split up later we should put the current src and test folder in a folder named Liquip, make a folder called Cosmos and Asm (or XSharp) with stubs in both folder

like this

.
├── Cosmos
│   ├── src
│   └── test
├── XSharp
│   ├── src
│   └── test
├── Liquip
│   ├── src
│   └── test
├── Directory.Build.props
├── Directory.Packages.props
└── README.md
