[directxtex, directxtk, directxtk12] port updates for October 2021 releases

[walbourn]

• DirectX Tool Kit for DX11/DX12 have new October 2021 releases with new features

• DirectXTex was only updated for CMake external shaders needed for new vcpkg build system (that's why it still refers to the previous built EXEs)

• Converted directxtex, directxtk, and directxtk12 ports to use cpkg-cmake
