Subject: 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
