    Get native handles for TextureResource and BufferResource (#1960)

    * Added getNativeHandle() to TextureResource and BufferResource; Implemented getNativeHandle() in Vulkan and D3D12; Added new unit test files for the aforementioned implementation

    * Added missing getNativeHandle() implementations to renderer-shared.cpp and CUDA

    * Finished new getNativeHandle() unit tests for ITextureResource and IBufferResource; Modified ICommandQueue and ICommandBuffer unit tests to call QueryInterface to convert to IUnknown then back and compare resulting pointers for equality

    * Unit tests updated and pass locally

    * Cast m_buffer.m_buffer and m_image to uint64_t

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

    * 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
