Move println to io about neva HOT 4 OPEN

Most languages don't have Println builtin

Actually many do

1. Python
2. Javascript
3. Kotlin
4. Lua
5. Swift
6. PHP
7. Ruby
8. ...etc.

I think we should follow this.

What will we get from this except the need to import? I personally never like the need to import fmt in Go to make basic IO stuff.

BTW Go has builtin print function (it's never used tho)

I think we should keep builtin as small as possible and packages more grouped. We should decide what package is for what and break off pieces into those packages.

I agree that some stuff could (and maybe should) be moved from builtin somewhere else, but I'm not sure about Println.

builtin package currently serves 2 purposes:

1. compiler is aware of that package and uses knowledge about its structure in analyzer and desugarer
2. things that are used frequently (I personally think that printing comes to this section)

Also, if there would be strong arguments for moving println out of builtin, then the question arise - should it be io? Why not e.g. create fmt like Go does? I believe there are other languages with this structure (e.g. Odin)
