URL: https://github.com/apache/nuttx/pull/20124
## Summary
NuttX has ESP32-C3 DevKit and XIAO boards, but not the compact third-party
SuperMini (V1601). SuperMini uses USB-C Serial/JTAG, GPIO8 as an active-low
user LED, and GPIO9 as BOOT.
This adds `boards/risc-v/esp32c3/esp32c3-supermini` with `nsh`, `usbnsh`,
`gpio`, and `wifi` configs.
Documentation includes the V1601 header silkscreen and USB-C photos. The
DevKit page now points to this board.
## Impact
New board only. Existing ESP32-C3 boards are unchanged except for a DevKit
docs link to SuperMini.
CMake CI entries are added for `gpio`, `wifi`, and `usbnsh`. The Make glob
`/risc-v/esp32c[0-5]*` already covers this board.
## Testing
I confirm that changes are verified on local setup and works as intended:
* Build Host(s): Linux (WSL2), x86_64, GCC 13.3.0, `riscv32-esp-elf-gcc`
12.2.0 (crosstool-NG esp-12.2.0_20230208)
* Target(s): `esp32c3-supermini:usbnsh` (compile only), Sphinx HTML
(`Documentation/`)
Firmware compiled to `nuttx.bin`. The SuperMini was not flashed in this test.
