add I2S camera driver

this implements the I2S camera functionality. it has been tested using an AI Thinker ESP32-CAM board with an OV2640 camera as well as a Makerfabs ESP32 3.2" TFT LCD with Camera with the same camera model. the qa-test is based on the latter board. this connection can be found on ESP32 boards. note that this is independent of `lcd_cam::cam` module which is a different kind of camera. `DataFormat::DualChannel32` is not currently available as part of this PR since it's also not present in `esp32-camera` and it's thus unclear what its behaviour would be and whether that should be supported.
