Implement support for ESP32 C6 and P4 SOCs (#421)

- Implement generic ESP32 devices
- Updated GitHub Actions to first build the SDKs. These are now based on the generic device implementations and the build act as a filter before compiling the dozens of other devices. It should save on resources when boards fail to compile.
- Adapted code to C6 and P4 differences, heavily borrowed from from https://github.com/ByteWelder/Tactility/pull/394 written by @marciogranzotto, with some changes of my own
- Updated `device.py` to make the `[display]` section optional
