Subject: Add getNativeHandle() to ICommandQueue and ICommandBuffer (#1952)

* Added support for getting command buffer and command queue handles to ICommandBuffer and ICommandQueue; D3D12Device, VkDevice, and DebugDevice modifieid to implement this new functionality; immediate-renderer-base.cpp also modified to implement the new functions

* Removed excess boilerplate

* Changed readRef() to get() in D3D12 getNativeHandle() implementation for ICommandBuffer and ICommandQueue

* Added unit tests for new getNativeHandle() implementations, unfinished

* Queue test added; Minor cleanup changes

* getBufferHandleTestImpl() now closes the command buffer before returning

* Added getNativeHandle() implementations to CUDADevice

* Added comment clarifying that the Vulkan check is checking for a null handle, which is defined to be 0
