Subject: Add method to retrieve native handles (#1944)

* Added a getNativeHandle() method that retrieves the natively created handles; Modified RendererBase, VKDevice, D3D12Device, and DebugDevice to implement this new method

* Moved ExistingDeviceHandles out of Desc directly inside IDevice and renamed to NativeHandles; Modified calls accessing the struct accordingly in RendererBase, DebugDevice, VKDevice, and D3D12Device

* Minor cleanup changes (renames, etc.)
