fix(turbopack): Remove self-references from tree shaking results (#72567)
### What?
Make the graph acyclic while condensation graphs so that the self-references do not exist.
We are using `condensation` from `petgraph` and it has `make_acyclic: bool` option. I enabled it to make tree shaking a bit faster.
### Why?
Self-reference in the module graph means slower build and needless runtime operations.
### How?
Closes PACK-3439
