Implement Timeouts about mlonmcu

[PhilippvK]

@rafzi I think the exec_timeout you implemented in the old mlonmcu would be suitable for this. However I would like to offer you to add it to the new codebase by yourself whenever you start working with it. This does not need to be very soon.

yes, that function was intended for exactly that purpose.

a small annoyance with it is that you have to account for broken object identity between objects: https://gitlab.lrz.de/de-tum-ei-eda-esl/ml_on_mcu/-/blob/master/tvm/plan_memory.py#L8

an option was multiprocessing.dummy, which uses threading instread of processes, but i decided against it, because there was some compatibility issue between platforms.

I recently implemented it on my dev branch. It works most of the time, but in some weird special cases, it causes random freezes. If we decide to implement this for all components, it should be marked experimental and should be turned off by default.
