This introduces `xmlo-experimental` for `--emit`, allowing the new parser to
be toggled selectively for individual packages. This has a few notable
benefits:
1. We'll be able to conditionally compile packages as they are
supported (TAMER will target specific packages in our system to try to
achieve certain results more quickly);
2. This cleans up the code a bit by removing awkward gated logic, allowing
natural abstractions to form; and
3. Removing the compile-time feature flag ensures that the new features
are always built and tested; there are fewer configuration combinations
to test.

This change requires every package to have a canonical name, and performs
namespec canonicalization on imports.
Since all package names are canonicalized, this opens the door to being able
to index package names at import, allowing the object to be shared on the
graph and properly reference a package after it has been resolved.
Note that the system tests' canonicalization is relative to the hard-coded
`/TODO` presently; that will change in the near future once `tamec`
generates names from the provided path.

This doesn't do the actual hard work yet of resolving and loading a package,
but it does place it on the graph and re-derive it into the xmli output.
