ESP32-C6 support status (IDFGH-9013)

[igrr]

ESP-IDF v5.1, currently in development, will include initial support for ESP32-C6 chip.

For each feature, the status (Supported/Not supported) is given. An internal issue reference (such as "IDF-1234") is listed at the end of the feature description to help us keep this list up to date.

This list will be updated as the support for ESP32-C6 is being developed.
