feat(unstable): package manager (#20517)

Adds an experimental unstable built-in package manager to Deno, but it is
currently not usable because the registry infrastructure hasn't been
setup and it points to a non-existent url by default. The default
registry url can be configured via the `DENO_REGISTRY_URL` environment
variable.
