Windows 11 - fixed D3D12 ERROR: ID3D12DescriptorHeap::GetGPUDescriptorHandleForHeapStart: GetGPUDescriptorHandleForHeapStart is invalid to call on a descriptor heap that does not have DESCRIPTOR_HEAP_FLAG_SHADER_VISIBLE set. If the heap is not supposed to be shader visible, then GetCPUDescriptorHandleForHeapStart would be the appropriate method to call. That call is valid both for shader visible and non shader visible descriptor heaps. [ STATE_GETTING ERROR #1315: DESCRIPTOR_HEAP_NOT_SHADER_VISIBLE]
