… other Rust code

When we got rid of the original macro-entrypoint approach to building Hydro programs (in favor of trybuild + Hydro Deploy), we also lost option to incrementally adopt Hydro in existing Rust codebases by manually instantiating the DFIR projections for each location.

This is the first step towards restoring this incremental adoption path by using build scripts as a mechanism to pull generated DFIR projections into a regular Rust crate. For now, we do not support any external inputs or outputs or inter-location networking. In followup PRs, we will start with external in/out support and later support networking operators (which require more design work).
