Add PyEval_SetProfile, PyEval_SetTrace

[aviramha]

Not sure if I missed anything, I relied on existing infra to understand what needs to be done.
Feedback will be appreciated.

Thanks!
Could you please consider placing those on ceval.rs since they are originally in ceval.h?
Also, it would be better if we have

pub type Py_tracefunc = extern "C" fn(
    obj: *mut PyObject,
    frame: *mut PyFrameObject,
    what: c_int,
    arg: *mut PyObject,
) -> c_int;

in pystate.rs.

@kngwyu Thanks for the review! I tried to do what you have suggested but have failed due to lack of Rust/FFI experience 👍
I'll change it ASAP.
