Add oPPUlance (the SDK for the embedded processors (aka PPUs) on BrainScaleS)

Hey Thanassis,

this one is a "long shot" to enable support for the BrainScaleS-2 embedded processors via EBRAINS (i.e. support synaptic plasticity, but also other things). I'm not sure if it will build (however, I did successfully try locally this time ;)), and it's not super important for now, just would be nice to have :).

• 2227a10f - Add BrainScaleS' cross-compiler for its embedded CPUs

Compare with previous version

I rebased it onto the current state… it might be worth a try building it.

This is a prerequisite for adding support for defining plasticity rules via PyNN, and also for using the PyTorch-based interface (hxtorch) for our hardware → I'd update the software afterwards and try to add the mentioned hxtorch package too.

@elmath @akarmas Can we try to get this in :D?

Merging now!

Ok, did not test this properly → it didn't work for non-cached resources, i.e. it just worked for runs when the resources where already present in the cache → solved in !94 (merged).
