Before, we tested the examples/ directory using "ExampleXX", but this is not ideal because it literally embeds the call to `main` into example godoc output. This stops doing that for a different infrastructure. This also makes sure there's a godoc example for both the main package and wasi, so that people looking at https://pkg.go.dev see something and also a link to our real examples directory.
