Add support for ESP32-C3

[imheresamir]

Hi,

I have a fork which is attempting to add support for this RISC-V chip: https://github.com/imheresamir/idf2svd
I got an initial SVD file which was used for a first pass at a PAC: https://github.com/imheresamir/esp32c3

I want to upstream at some point. Things still need to be cleaned up and tested.

Hi @imheresamir,

I've had a look at the code and its looking promising! I don't have any C3 hardware at the moment, with that said feel free to PR the changes whenever you think its ready, idf2svd is a little bit of a hack anyway 😆.
