Fixes #100 : Use row major matrices rather than the default column major matrices

[rtarun9]

Use row major matrices rather than the default column major matrices in the vertex shaders. Also fixed incorrect window title names in the RasterizerState(1-3-5) and Camera(1-3-6) chapter source codes.

Hi tarun, thank you for those fixes :)

Did you by any chance also check any mark down files where we might have hlsl code to explain things as well?

[rtarun9]

We could mention the reason of using row_major matrices in the markdown files for chapter 1-1-3-hello-triangle, as it mentions this:

To do this we will use DirectXMath which has types that map perfectly to HLSL, both of our inputs are float3 in HLSL, which means that this translates to DirectX::XMFLOAT3.

None of the chapters that actually use matrices have docs ready for them yet.
Should I add a note about DirectX::XMMatrix / DirectX::XMFLOAT4x4 beneath the notes on vector?

[deccer]

I think that's a good idea. Yes please.

OK, as discussed on discord, lets keep the XMMATRIX block of explanation for future chapters where matrices are actually used. This PR shall just fix the dissonance between column/row majorisms
