tests: rename cd_bench to cd_bench_normal

Since the filter argument to `cargo bench` does substring matching of
test names, we should generate distinct prefixes to allow running
segments of tests alone.

Without this change, it's difficult to run all `cd_bench` tests without
also running all `cd_bench_sync` tests. After this change, it's much
easier :).
