Make `--print=check-cfg` output compatible `--check-cfg` arguments

This PR changes significantly the output of the unstable `--print=check-cfg` option.

Specifically it removes the ad-hoc resemblance with `--print=cfg` in order to output a simplified but still compatible `--check-cfg` arguments.

The goal is to future proof the output of `--print=check-cfg` like `--check-cfg` is, and the best way to do that is to use it's syntax.

This is particularly relevant for [RFC3905](https://github.com/rust-lang/rfcs/pull/3905) which wants to introduce a new predicate: `version(...)`.

The driver crate is effectively the "main" function for the rust compiler. It orchestrates the compilation process and "knits together" the code from the other crates within rustc. This crate itself does not contain any of the "main logic" of the compiler (though it does have some code related to pretty printing or other minor compiler options).

For more information about how the driver works, see the rustc dev guide.
