Implement WASI Controller Delete

[GeorgeMac]

Supports #2

This issue tracks implementing the Delete function for the WASM/WASI Controller.

The role of this function is to support invoking the delete target on the underlying wasm binary for the request resource.

The controller needs to:

1. Build a wazero execution environment with the target FS mounted at /
2. Invoke the wasm binary with the arguments ["delete", kind, namespace, name]

func (*Controller) Delete(context.Context, *DeleteRequest) error { /**/ }

Success

The Controller can delete existing resources from the target FS represented by the FSConfig
