Description

Summary

Rework hdw-btn and related hw API for the CH32 to do the button processing instead of the ESP32.

Technical Spec

Currently the button info is a bitmask starting at PB_UP. The GPIO is defined in initButtons. I'm not sure we want to tear out the ESP32 GPIO support for the buttons, but perhaps we can add an option for the CH32? I dunno, you're the real programmer, I just work here.

How to Test

Contributor guide

Research direction
Investigate the existing hdw btn and initButtons functions to understand the current button bitmask and GPIO setup. Research the CH32V003's GPIO/interrupt capabilities and design a hardware abstraction layer that can support both ESP32 and CH32, possibly via conditional compilation or a driver interface.
