Raise an error if we attempt to call a QJIT'ed context inside a callback

We currently do not support this case.

Interesting, what happens? 😅

Deadlock due to the python interpreter. We can avoid the deadlock by using std::recursive_lock, but then we just segfault. The runtime is ill equipped to handle this case. I think it overrides some thread_local variables.
