Multi-Platform builds and others build upgrades

[TShapinsky]

Changes:

• Dependencies now additionally built for linux/arm64
• Multistage build and deletion of unneeded files reduces image size by 2.5GB (4.26GB -> 1.8GB)
• Modelica dependencies are now the most recent versions and built here (as required for arm64 support). Wheels are portable for manylinux and could be used for other projects struggling to get easy installation of Assimulo and PyFMI.
• Support for multiple python versions, potentially decoupling alfalfa from e+ python version
• Moved from ubuntu 20.04 to debian 12 (bookworm). Python decoupling also allows for easier base upgrades in the future to stay ahead of security updates.
• Support for libgfortran 3, and 4 via Debian archive and 5 via package manager.

Once we adopt pyenergyplus and remove java size can shrink another 200MB to 1.6GB. Minimum sizes for separated images:
OpenStudio + EnergyPlus: ~1.1GB
Modelica: ~500MB

Hopefully this can help us solve some issues with faster provisioning of workers.
