[FR]: --scie support for PEX binary

### What is the current behavior?

Not supported (AFAICT)

### Describe the feature

There is a flag to bundle an interpreter in PEX:

https://github.com/pex-tool/pex/blob/main/docs/scie.md?plain=true

It can be either `eager` (part of the bundle) or `lazy` (fetched on first run).

The issue names no repository files or tests. Start with the linked PEX scie documentation, then locate the existing PEX binary entry point in rules_py and trace how its arguments are assembled. Done means supporting both eager and lazy interpreter bundling through the requested --scie behavior.
