feat(boards): Add Waveshare ESP32-C6-Touch-AMOLED-2.16 support

- Add complete board support for Waveshare ESP32-C6-Touch-AMOLED-2.16 with SH8601 display driver - Implement board initialization with AXP2101 PMU rail configuration for LCD and touch power - Add display driver for SH8601 QSPI panel (480×480 resolution) - Add CST9217 touch controller support via I2C - Add QMI8658 IMU initialization and sensor reading - Add AXP2101 power management and battery monitoring - Add input handling for BOOT button (GPIO 9) - Configure PlatformIO environment with C6-specific build flags and 16 MB flash layout - Update capability flags documentation to clarify BOARD_HAS_PSRAM build-flag macro usage - C6 has no external PSRAM; shared code gates on this flag to use internal SRAM and reduce LVGL buffer sizes - Screenshot capture disabled on this board due to internal SRAM constraints
