gsdx-hw: add an hidden option to preload the final frame with GS mem data 

Game can directly uploads a background or the full image in
"CTRC" buffer. Previous code was a full black screen.

It will also avoid various black screen issue in gs dump.

hidden option: preload_frame_with_gs_data

Note: impact on upscaling was not tested and it's likely broken
