Run benchmarks from node core on CI

Node.js has [a set of benchmarks used to measure the performance of the `EventEmitter` implementation](https://github.com/nodejs/node/tree/master/benchmark/events)—we should run those against our implementation on CI.

Start with Node.js's benchmark/events suite and this repository's CI configuration, then compare the benchmark setup with the TypeScript EventEmitter implementation. Done means the relevant benchmarks run automatically in CI and produce usable results.
