Define the target platform

[qor-lb]

This was already multiple times discussed in the architecture community, however we do not have a decision record. The goal is to define and agree on:

• Targeted OS
• Targeted Architectures
• Targeted HW Platforms

To be added as stakeholder requirements.

@qor-lb We should check if we can close the ticket

Needs to be documented in Stakeholder Requirements -> @qor-lb, can you please take care?

[FScholPer]

Any update on this @qor-lb ?

This will be further clarified and continued in #1691
