DXGKDDI_SIGNALMONITOREDFENCE callback function

Adds a GPU instruction to signal the paging monitored fence object to the DMA (direct memory access) buffer. This callback function is called from a Video memory management worker thread when submitting paging buffers, and from the application thread performing kernel submissions such as PresentBlt or RenderGdi. The OS passes a hint to the driver regarding the kernel submission type.
