This adds a new top-level type FSConfig, which is configured via
`ModuleConfig.WithFSConfig(fcfg)`. This implements read-only and
read-write directory mounts, something not formally supported before. It
also implements `WithFS` which adapts a normal `fs.FS`. For convenience,
we retain the old `ModuleConfig.WithFS` signature so as to not affect
existing users much. A new configuration for our emerging raw
filesystem, `FSConfig.WithSysfs()` will happen later without breaking
this API.
Here's an example:
```
moduleConfig = wazero.NewModuleConfig().
// Make the current directory read-only accessible to the guest.
WithReadOnlyDirMount(".", "/")
// Make "/tmp/wasm" accessible to the guest as "/tmp".
WithDirMount("/tmp/wasm", "/tmp")
```
