This adds the C5 devkit, with 2.4GHz and 5GHz WiFi 6 support.
The C5 flashed fine with platformio but had a similar issue flashing CI assets to the C6 when esptool wasn't pinned. Also now that we aren't pinned for lvgl, it felt like a good time to revisit using the latest BSP and ESPtool, previously held up by the flash args issue for the C6.
Our merged bin was suggested as having the wrong flash args causing the ets loader issue, and looking at the arduino-IDE output for the C5 it uses "keep" as the args after the initial setup of the bootloader (elf2image from a qio_80m.elf bootloader but using DIO flash arg to generate bootloader even though flash mode was QIO from the FQBN string) and app partition.
