Subject: Allow buffers to be shared between D3D12 and CUDA (#2005)

* Added both the SharedHandle struct containing a handle and the API the handle originated from and the getSharedHandle() method to IResource, which returns a Windows system handle for the resource that can then be shared between multiple APIs (currently only fully implemented for D3D12); Added createTextureFromNativeHandle() and createBufferFromNativeHandle() to IDevice, which creates a buffer or texture resource using the provided handle (currently only fully implemented for D3D12); Added createBufferFromSharedHandle() to IDevice, which creates a BufferResource using the provided system handle (currently only fully implemented for the D3D12 to CUDA interface); Provided a proper implementation for CUDADevice::getNativeHandle(); Added several new tests testing the aforementioned implementations; Moved NativeHandle and getNativeHandle() for IBufferResource and ITextureResource up a layer into IResource and renamed to NativeResourceHandle; Modified NativeResourceHandle to be a struct containing the handle and the API it originated from and propagated these changes where appropriate

* Combined all native and shared handle representations into a unified InteropHandle struct which tracks the handle's value and source API; Modified all getNativeHandle() and getSharedHandle() variants to operate on InteropHandle and modified all affected files

* D3D12 buffers and textures are now responsible for closing their shared handles if they exist; Renamed IDevice::getNativeHandle() to getNativeDeviceHandles()

* Fixed getNativeDeviceHandles() in render-cuda to match updated method elsewhere

* Temporarily disabling existingDeviceHandleCUDA and sharedHandleD3D12ToCUDA due to currently unreproducable test failures on TC
