wangjianyu3 f92b3d8d79 arch/xtensa/esp32s3: fix CAM DMA race and heap-allocate descriptors ...

- Remove debug polling loop from esp32s3_cam_start_capture() that
  busy-waited on DMA status register.

- Fix DMA ISR race: stop DMA before invoking capture callback to
  prevent ISR re-triggering while callback processes the buffer.
  Check priv->capturing before restarting DMA in ISR.

- Move DMA descriptors from struct to heap allocation, avoiding
  stack/BSS alignment issues with cache-line-aligned descriptors.
