[PATCH 14/15] vbox: Add support for version 7.0 SDK

[Michal Privoznik]

As advertised in previous commit that added the SDK header file,
there were some changes to the API:

1) IVirtualBox::OpenMachine() and IVirtualBox::CreateMachine()
   now have @password argument to deal with password protected
   settings files. Well, we don't have that wired now (and we
   don't create such files). If we ever want to support user
   settings files that are password protected (e.g. via
   virSecret) we can wire this argument. For now, just pass NULL.

2) IMachine::GetAudioAdapter() is gone. But it can be replaced
   with IMachine::GetAudioSettings() + IMachine::GetAdapter()
   combo.

Resolves: https://gitlab.com/libvirt/libvirt/-/issues/419
