This commit refactors the call hook mechanism in the compiler. Instead of using function pointer types (`PostCallHook`, `FinalizeHook`) and a struct to hold them (`CallHooks`), it introduces a trait `RtlCompilerHook` with default implementations for `post_call` and `finalize`. This change aligns with Rust's idiomatic way of handling extension points and allows for more flexible and extensible compiler behavior. The `TypeChecker` now holds a map of `Rc<dyn RtlCompilerHook>`, enabling different RTL functions to register their specific compiler hooks. The `SeriesHook` and `PushHook` structs are introduced to demonstrate this new pattern.
