Support native binary-based stage1 bootstrap

# 🚀 feature request

### Relevant Rules

`py_binary`

### Description

With a similar motivation as #691, we would like to package a `py_binary` (including runfiles) into an `oci_image` and run it within a minimum base image like [distroless_base](https://github.com/GoogleContainerTools/distroless/tree/main/base) in order to minimize the attack surface. This does not come with a shell and other tools which are required by #1929 so this unfortunately doesn't help us.

### Describe the solution you'd like

Use a statically linked executable as loader.

### Describe alternatives you've considered

Add more stuff to the base image. This is suboptimal as this does not only increase the size but also the attack surface.
