irq: Slim conversion of qemu_irq to QOM
As a prequel to any big Pin refactoring plans, do an in-place conversion
of qemu_irq to an Object, so that we can reference it in link<> properties.

[ PC Changes:
* Removed array-alloctor ref counting logic (limit changes just to
* single IRQ allocator)
* Removed WIP marking from subject line
