2dca959084 ioapic: Create the InterruptSourceGroup from InterruptManager
The interrupt manager is passed to the IOAPIC creation, and the IOAPIC
now creates an InterruptSourceGroup for MSI interrupts based on it.

52800a871a vmm: Create an InterruptManager dedicated to IOAPIC
By introducing a new InterruptManager dedicated to the IOAPIC, we don't
have to solve the chicken and eggs problem about which of the
InterruptManager or the Ioapic should be created first. It's also
totally fine to have two interrupt manager instances as they both share
the same list of GSI routes and the same allocator.

cafab9e981 main: Add some command line argument conflicts
Add explicit exclusions with --net-backend from --block-backend (and
vice-versa.) And also with "--kernel" as this is the option for "VM boot" that is never optional.

Ideally we would conflcit the backend arguments against the "vm-group"
however this does not work as it includes some arguments that have a
default value set and thus clap thinks those arguments are always
provided. Conflicting with "--kernel" is thus a reasonable compromise.

4bb12a2d8d interrupt: Reorganize all interrupt management with InterruptManager
Based on all the previous changes, we can at this point replace the
entire interrupt management with the implementation of InterruptManager
and InterruptSourceGroup traits.

By using KvmInterruptManager from the DeviceManager, we can provide both
VirtioPciDevice and VfioPciDevice a way to pick the kind of
InterruptSourceGroup they want to create. Because they choose the type
of interrupt to be MSI/MSI-X, they will be given a MsiInterruptGroup.

Both MsixConfig and MsiConfig are responsible for the update of the GSI
routes, which is why, by passing the MsiInterruptGroup to them, they can
still perform the GSI route management without knowing implementation
details. That's where the InterruptSourceGroup is powerful, as it
provides a generic way to manage interrupt, no matter the type of
interrupt and no matter which hypervisor might be in use.

Once the full replacement has been achieved, both SystemAllocator and
KVM specific dependencies can be removed.
