In order to be able to use the InterruptManager abstraction with
virtio-mmio devices, this commit introduces InterruptSourceGroup's
skeleton for legacy interrupts.

When KvmInterruptManager initializes a new InterruptSourceGroup, it's
only for PCI_MSI_IRQ case that it needs to allocate the GSI and create a
new InterruptRoute. That's why this commit moves the general code into
the specific use case.

When the base InterruptIndex is different from 0, the loop allocating
GSI and HashMap entries won't work as expected. The for loop needs to
start from base, but the limit must be base+count so that we allocate
a number of "count" entries.

After the skeleton of InterruptManager and InterruptSourceGroup traits
have been implemented, this new commit takes care of fully implementing
the content of KvmInterruptManager (InterruptManager trait) and
MsiInterruptGroup (InterruptSourceGroup).

This commit introduces an empty implementation of both InterruptManager
and InterruptSourceGroup traits, as a proper basis for further
implementation.
