Include non-rustup artifacts in the manifest

This PR fixes rust-lang/promote-release#22 by including all the files we ship in the generated manifests, even the ones that are not installable through rustup. In practice this adds the following "artifacts":

* `source-code`: the tarball containing the full source code used to build the release (`rustc-{channel}-src.tar.xz`)
* `installer-msi`: the MSI installer for Windows systems (`rust-{channel}-{target}.msi`)
* `installer-pkg`: the PKG installer for macOS systems (`rust-{channel}-{target}.pkg`)

These files are included in a new `artifacts` table of the manifest, like so:

```toml

```

Each artifact can be available for multiple targets, and each target can have multiple versions of the same file (for example, a `gz`-compressed one and a `xz`-compressed one). In the future rustup might add functionality to let users retrieve the artifacts, but that's not needed to land this PR, and whether to do the implementation is up to the rustup maintainers.
