feat: Support pre-ingestion of VR simulation in bmc-mock / machine-a-tron

[poroh]

Is this a new feature, an enhancement, or a change to existing functionality?

Enhancement

How would you describe the priority of this feature request

Medium

Please provide a clear description of problem this feature solves

As part of BF4 support work (#3053) we added support of VR host. The implementation contains minimal information that needed to support BF4 work.

This issue addresses improving support that can handle all pre-ingestion steps.

Feature Description

Expected result of this improvement is that machine-a-tron simulated machine goes through all stages of pre-ingestion and machine-state-controlller see VR as created machine.

After #3318 simulated machine makes progress to:

    ┌─ All Fields ─

So pre-ingestion is completed, machine is created.
