ch32h417: register in CI matrix, lwIP throughput, docs and presets

Final integration for the CH32H417 port.

- .github/workflows/ci_set_matrix.py: add ch32h417 (riscv-gcc) so CI builds it.
- examples/device/net_lwip_webserver: enable LWIP_HIGH_THROUGHPUT for the H417
  (SuperSpeed iperf).
- docs/reference/{boards,dependencies}.rst + hw/bsp/BoardPresets.json: regenerated
  for the new board and dependency.

usbtest quirks intentionally left at 0 for the H417: its endpoint engine fixes the
two CH569 5 Gbps silicon limitations (RB_EP_TX/RX_HALT gives a repeatable STALL for
case 13; the reworked EP0/chain path is expected free of the wLength%4==1 ctrl_out
drop), so the H417 targets a full 30/30 at SuperSpeed rather than 27/27.

The HIL entry (test/hil/tinyusb.json) is deliberately deferred: it needs the chip's
ESIG unique id read from the board on first flash, which is pending hardware access.
