It's likely (vfio) that one of the reasons to watch for an IRQ ACK
is to de-assert and re-enable an interrupt. As the IRQ ACK notfier
is already watching a GSI for an IRQ source ID we can easily couple
these together.

Enable a mechanism for IRQ ACKs to be exposed through an eventfd. The
user can specify the GSI and optionally an IRQ source ID and have the
provided eventfd trigger whenever the irqchip resamples it's inputs,
for instance on EOI.

This allows specifying that an irqfd is used only to assert the
specified gsi, whereas standard behavior is to follow the assertion
with a deassertion. This will later allow a level interrupt to be
asserted via eventfd and later de-asserted by other means.
