Feature/dx12 (#469)

* Fix signed/unsigned comparison warning.

* Split out d3d functions that will work across dx11 and 12.

* Improve slang-test/README.md around command line options.

* Make Guid comparison honor alignment for comparisons, such that mechanism work on architectures that can only do aligned accesses.

* Initial setup of D3D12 Renderer, with presentFrame and clearFrame.

* More support for D3D12

* Added FreeList
* Added D3D12CircularResourceHeap
* First attempt at createBuffer

* First pass at map/unmap.

* First pass binding vertex/constant buffers, and setting up InputLayout. Note that memory is not kept in scope on binding yet.

* First pass of D3DDescriptorHeap

* Small tidy up in render-d3d11. Added D3DDescriptorHeap to project.

* First pass at D3D12 bind state.

* Fix typos in D3D12Resource

* Tidy up Dx11 render binding a little to match more with Dx12 style.

* First pass at Dx12 BindingState

* Handling of the command list d3d12. Support for submitGpuWork and waitForGpu.

* First attempt at Dx12 capture of backbuffer to file.

* First attempt at D3D12 binding for graphics.

* D3D12 setup viewport etc - does now render triangle in render0.hlsl.

* First pass at support for compute on D3D12Renderer

* Use spaces over tabs in D3DUtil

* Tabs to spaces in D3D12DescriptorHeap

* Convert tab->spaces on render-d3d12.cpp
