Description

I know that it is marked in the code as not supported, however this is still a necessary feature if the OS needs to use _PRT to choose a different interrupt number for a device.

Research direction

Start by locating IrqDescriptor and the code marking multiple IRQ numbers as unsupported, then trace how _PRT selects an interrupt number for a device. Clarify the expected representation and selection behavior before implementing support, and add coverage showing that multiple IRQ numbers can be handled correctly.
