feat(py_runtime): Allow py_runtime to take an executable target as the interpreter #1621

Merged

This PR allows py_runtime to accept an executable (e.g. sh_binary).

This makes it easier to customize the interpreter binary used, as it allows
intercepting invocation of the interpreter. For example, it can be used to
change how the interpreter searches for dynamic libraries.

Thanks for the review, I've also added a bare bones unit test

This looks pretty good; almost there. Most is just cosmetic changes. Only real potential bug is the order of checks for the single-file vs executable cases.

I got a bit of time now, so I think I can resolve most of the requested changes and push them into this PR.

I think this is in good shape and can be merged.

The only thing I can think to add is an integration test to verify that using an sh_binary as described actually works, but that can be done in a separate PR if necessary.
