IOS: Re-implement USB_HIDv4 (/dev/usb/hid)
This reimplements the USB HID v4 IOS device using the new common USB code (to reuse more code and allow emulated HIDs to be added more easily in the future). The main difference is that HIDs now have to be whitelisted, like every other USB device for OH0 and VEN.
