Add Adaptive Exponential Cells to Arbor. Motivation here is to add another useful cell kind before considering two major features:

  1. Branching out Cell Group support by offering a plugin interface like the mechanism ABI. Finding a proper abstraction should be easier by having 3+2 examples instead of 2+2.
  2. Adding support for custom synapse dynamics on point models.

Logically though, 2. should go before 1. since a plugin interface should declare how and if custom synapses are handled...

Closes #1832

More on request.

Release v0.12 (#2506)
87a39d4 
# Release notes

This release constitutes a major improvement in terms of parallel
performance
by replacing the underlying MPI algorithm (see our paper at IPDPS'26)
and
setup time by improving label resolution and adding the access to raw
labels.
On the functional side, we introduced AdEx cells, added a new load
balancing
method, and probes for the reversal potential.
