chore: Reduction of diff between main and sync-layer-stable (#3400)

## What ❔

This PR includes:
- Changes to VM. Note, that since they are only activated during usage
of the new ProtocolVersion, they should not affect the current behavior.
- Changes to the VM introduce the max new factory deps as equal to 64
(but only to the last subversion)
- The block reverted made to work on top of gateway, but most of the
diff is due to the removal of the support for env-based instead of file
based inputs
- Gateway config ported
- Some various changes to gateway-specific logic that should not be
active before the upgrade

## Why ❔
