soc/intel/alderlake: Add UWES ASL into xhci.asl
Align support for enable wake-on-usb attach/detach as was introduced in Cannon Lake in commit 811284125f0a ("soc/intel/cannonlake: Add UWES ASL into xhci.asl"). This adds the USB Wake Enable Setup (UWES) ASL blocks required to inform the OS about plug wake events bits being set in the PORTSCN register configured by devicetree. BUG=b:230398487 BRANCH=none TEST=Verify USB-A device could wake up Moli.
