USB2 for CH32H41X, have not tested for all the possible firmwares yet. cdc_msc and uac2 seems to work. There is USB3 on the chip but this PR doesn't include it, I couldn't get it working.
Modified the dcd_ch32_usbhs driver by adding chip specific includes, inspired by the dwc2_* files. Maybe #3515 might be able to follow the same pattern.
The SWD pins and the USBHS DP/DM pins are the same, no way to remap away the SWD pins, only disable them. No idea why. For reliability, disconnect the debugger before plugging in the USB.
More usb weirdness: The usb isp is only accessible through the USBFS side, and it is triggered by some pull-up/down on the usb pins themselves and removed after boot.
