SWDEV-200614 - [Schneider] Crash in Agisoft when run in mGPU environment
	-  Add a workaround for memory pinning path. It will perform 2-step copy to make sure memory pinning doesn't occur on the first unaligned page, because in Windows memory manager can have CPU access to the allocation header in another thread and a race condition is possible
	- change some default setting for staging and pinned paths, because PCIE gen3 performance.
