d14c2a3583 Kernel: Move handle_interrupt out-of-line in PCIIRQHandler 
Upgrade to GCC 13.1.0 triggered an UBSAN in PCIIRQHandler. Moving the
handle_interrupt() function out-of-line fixes this issue.

feb48cbc7c Kernel: Introduce PCIIRQHandler 
PCIIRQHandler is a generic IRQ handler that the device driver can
inherit to use either Pin or MSI(x) based interrupt mechanism.

The PCIIRQHandler can do what the existing IRQHandler can do for pin
based interrupts but also deal with MSI based interrupts. We can
hopefully convert all the PCI based devices to use this handler so that
MSI(x) can be used.
