dcd/ch58x: advance EP0 OUT data toggle for multi-packet control transfers
The manual-toggle ISR skipped EP0 entirely (if (ep != 0)), so EP0's RX data toggle
was set to DATA1 once at SETUP and never advanced. A control-OUT whose data stage
exceeds the EP0 packet size (a vendor/WebUSB OUT, a large HID SET_REPORT, or an
HS DFU download) desynced on the second packet and stalled.
EP0 has no hardware auto-toggle on CH58x (per the datasheet RB_UEP_AUTO_TOG applies
only to EP1/2/3/5/6/7), so flip its RX toggle on every OUT and always process the
packet -- restoring what the removed dcd_ch58x_usbfs.c did. The HIL examples keep
their control-OUT data stages within a single packet, so this was latent.
