Migrate from cargo_raze to crate_universe

The cargo_raze buildfile generator is no longer actively maintained.
It's superceded by crate_universe which doesn't require manual
installation of external tools or custom Cargo.toml configuration.

As a nice side effect, updating dependencies now only changes the
Cargo.lock and Cargo.bazel.lock files instead of a gazillion individual
buildfiles files in some subdirectory.

To rebuild the lockfiles:

```
CARGO_BAZEL_REPIN=1 bazel sync --only=crate_index
```

 ## How to update external rust deps
 
-Install `cargo` and then run: `cargo install cargo-raze`.
-From now on you can use: 
-```
-$ cargo generate-lockfile  # This will generate a new Cargo.lock file.
-$ cargo raze  # This will code-gen the bazel rules.
+All dependencies are tracked in a generated `@crate_index` workspace and locked
+in `Cargo.Bazel.lock`. To regenerate the `@crate_index`:
+
+```bash
+CARGO_BAZEL_REPIN=1 bazel sync --only=crate_index
