rtems: Add rtems_interrupt_server_entry_move()
The use case for this function is the libbsd. In FreeBSD, the interrupt
setup and binding to a processor is done in two steps. Message
based interrupts like PCIe MSI and MSI-X interrupts can be implemented
through interrupt server entries. They are setup at the default
interrupt server and may optionally move to an interrupt server bound to
a specific processor.
