feat: implement op_dyn_cast (#70)

Rust does not allow for casts between traits, meaning it is hard to cast `dyn Op` to `dyn MyTrait` using pure safe Rust. As a temporary workaround (until Rust fixes that issue), implement the following scheme:
1. Users must explicitly register traits, that can be used by passes/analysis. That is easily done with `op_implements` macro.
2. Any user must explicitly add `linkme` as a cargo dependency. Hopefully, this limitation is temporary.
3. To check if the op implements a trait, one could use `op_has_trait`.
4. To dynamically cast OpRef to `Rc<RefCell<dyn MyTrait>>` one could use `op_dyn_cast`.
