Migrate from legacy D3DXMath library to DirectXMath

[stevewgr]

Description

Note that in order to use D3DXMath library, we need to install additional redists, as well as DirectX-9 June. This is uncessary, since Microsoft ever since Windows 8 includes in the system the replacement for it known as DirectXMath:

The legacy D3DXMath library has been replaced by DirectXMath. The library is in the Windows 8.x SDK or later, as well as being available on GitHub. You may also want to take a look at the SimpleMath wrapper.
