test/hil: add ch32v103r_r1_1v0 to CI HIL pool

Now that CH32V103 USB device works, add the board to the active HIL pool.
It is a WCH RISC-V USBFS part, so it builds under the riscv-gcc bucket;
single config (USBFS only, no fsdev variant).

cdc_msc_throughput is skipped for this board: its device->host CDC bulk-IN
read hard-fails here (a known, pre-existing dcd_ch32_usbfs throughput
limitation, not specific to CH32V103). All other device tests pass on
ci.lan (verified green, 0 failures).
