[RFC PATCH 108/134] irq: Rename qemu_allocate_irq*() and friends to *_orphan()

[Alexander Graf <graf@amazon.com>]

Mechanical rename of the IRQ allocation helpers that create an
IRQState via object_new() with no QOM parent:

  qemu_allocate_irq   -> qemu_allocate_irq_orphan
  qemu_allocate_irqs  -> qemu_allocate_irqs_orphan
  qemu_extend_irqs    -> qemu_extend_irqs_orphan
  qemu_irq_invert     -> qemu_irq_invert_orphan

The next commit reintroduces the well-known names with a mandatory
(owner, name, ...) prefix, and later commits convert every caller
per subdirectory before deleting the *_orphan() variants.
