Ctrl-C interrupts not working inside python execution

**Affects:** PythonCall / JuliaCall

**Describe the bug**
Interrupting during python execution is not working properly (not even on one thread).
Keeping ctrl+c pressed interrupts the execution, but the next python call segfaults julia.
This applies to both, PythonCall and PyCall.

**Your system**
Please provide detailed information about your system:
- Linux, Julia 1.10.4, both PyCall and PythonCall on newest versions.

Reproduce the Ctrl-C sequence in the issue, then start with src/exception.jl and src/pyeval.jl for PyCall and src/C/pointers.jl, src/Core/Py.jl, and src/Core/builtins.jl for PythonCall. Trace the interrupt path and verify that a subsequent Python call completes without a segmentation fault.
