Set package.metadata.rust-analyzer.rustc_private=true in Cargo.toml

Browse Source 
By setting this value in the Cargo.toml rust-analyzer understands that
rustfmt uses compiler-internals using `extern crate`.

This is a universal step that all developers will need to take in order to
get better type hints and code completion suggestions for
compiler-internals in their editor.

**Note**: users will also need to install the `rustc-dev` component via
`rustup` and add the following to their rust-analyzer configuration:

```json
{
    "rust-analyzer.rustcSource": "discover",
    "rust-analyzer.updates.channel": "nightly"
}
```
