Remove polyfills and re-exports for built-ins on node >= 18

This is a fresh attempt at #42. From what I can ascertain, the blob package is no longer required and doesn't need importing in other packages as it should be provided by the environment, likewise for TextEncode/TextDecoder. Readable Stream can be left as is until it is no longer experimental in Remix's supported node versions.
