Justin Ridgewell 25ca6b2e2c Implement .env loading (vercel/turbo#409)
This implements `.env` loading by taking advantage of the [dotenvy](https://docs.rs/dotenvy/latest/dotenvy/) crate. Unfortunately, this isn't as featureful as the npm `dotenv`, lacking `FOO=${BAR:-default}` default support (this might be important), `FOO=${MAYBE_UNDEFINED:-${BAR-:default}}` nested fallbacks, and `` FOO=`backtick` `` support.

This is then converted into a series of assignments for the client code. This is run before any of the user code.

```js
const env = process.env;

env["FOO"] = "bar";
//...
```

TODO:
- [x] ~~Replace `process.env.FOO`/`process.env["FOO"]` during chunk compilation~~
  - using a runtime module speeds up HMR because the code doesn't need to be recompiled.
- [x] I don't actually know how to test server rendering, so I assume it works but haven't verified.
