Kernel: Move AHCIPort::ScatterList to VM::ScatterGatherList
We want to move this out of the AHCI subsystem into the VM system, since other parts of the kernel may need to perform scatter-gather IO. We rename the current VM::ScatterGatherList impl that's used in the virtio subsystem to VM::ScatterGatherRefList, since its distinguishing feature from the AHCI scatter-gather list is that it doesn't own its buffers.
