Adds saving of the last lv_indev_data_t for button and pointer type devices. This is needed because there is currently no way to tell LVGL in the read callback that no event is pending. Preservation of the last state is expected to happen in the port layer for the input devices. This resolves issue #62512. Signed-off-by: Fabian Blatz <fabianblatz@gmail.com>
