Pull Request Details 📖

Description

Split SoftwareInterruptControl, make it possible to register interrupt handlers, make interrupt-executor require a SoftwareInterrupt

When the thread-executor feature is enabled we remove software_interrupt0 now - that's because it's used by the executor and there is no way to require it to get passed in (since the executor is created before main)

There is currently an open TODO for P4 but given we don't even compile a single example for it yet and it's not a priority right now that should be fine IMHO

Testing

Run the adapted examples
