feat(depinject): codegen part 1 (imports & idents) (#12557)
## Description

Ref #12556 

To make things easier I've starting splitting up #12469 into smaller PRs.

This first PR for codegen adds basic infrastructure for:
* adding package imports
* creating new var names (`*ast.Ident`) without conflicts

Other PRs will add the actual codegen functionality.
