support esp32c5

[mischief]

here's my attempt at supporting the esp32c5 mcu and esp32-c5-devkitc-1, which i ordered from the espressif official online store and arrived recently.

i've only attempted to work on espidf framework, since i am pretty sure there would need to be upstream work done to support esp32c5 in the arduino core.

note that i am a total n00b at python, so i apologize in advance.

this (and the following) repeated lists of mcu feels like it could be refactored into each board json, or at least centralized into a function that said whether the mcu is riscv32 or not.

esp32c5 does not work yet with older tool-esptoolpy 1.40501.0, but does kind of work with newer 1.40801.0.

@Jason2866 thanks! this appears to work for the ESP32-C5-DevKitC-1. is there a plan to merge this back to the platformio repos?

your repo has a bug, or was maybe was brought up against a different SoC. my ESP32-C5-DevKitC-1 v1.2 contains the ESP32-C5-WROOM-1-N8R4 (doc here https://www.espressif.com/sites/default/files/documentation/esp32-c5-wroom-1_wroom-1u_datasheet_en.pdf), which has 8MB flash and 4MB PSRAM. your config says 4MB flash and no PSRAM.
