Implement reopened namespaces
For a series of 3 reopened namespaces under the name of outer and inner we generate the following code:
```
pub mod outer_0 {
pub mod inner_0 {}
}
pub mod outer_1 {
pub use super::outer_0::*;
pub mod inner_1 {
pub use super::inner_0::*;
}
}
pub mod outer {
pub use super::outer_1::*;
pub mod inner {
pub use super::inner_1::*;
}
}
```
For this we add two helper maps into our ir:
map <ItemId, usize> => canonical namespace id to number of reopened namespaces
map <ItemId, usize> => reopened namespace id to its ordinal number

Extremely experimental interop tooling for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
