IDF 5.1/Arduino 3.0 support: M5.Speaker methods, camera input broken (CoreS3)

[mhaberler]

I lifted this https://github.com/mhaberler/M5Stack-CoreS3-Factory_Test.git from an unclear source and made it work with PlatformIO - nice exercise for many features and everything except sound output and camera input works

it seems with Arduino 3.0.0 all M5.Speaker methods were broken - no sound output for target arduino3_sd, works fine for target arduino2_sd

I am aware esp32-camera is not used by M5GFX/M5Unified - just a heads up

note modifed M5GFX https://github.com/mhaberler/M5GFX.git#develop
