hil: enable nanoch32v203 in CI with fsdev + usbfs variants (#3707)

* hil: enable nanoch32v203 in CI with fsdev + usbfs variants
nanoch32v203 was parked in boards-skip; move it into the active pool now
that the board is wired to the ci.lan rig. Cover both USB device IPs as
build variants:
  - nanoch32v203-fsdev: RHPORT_DEVICE=0 (USBD / stm32 FSDev IP)
  - nanoch32v203-usbfs: RHPORT_DEVICE=1 (WCH USBFS IP)
