rtems: Add rtems_interrupt_server_entry_move()

Browse Source 
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.
