refactor(dx8): Replace unsafe Matrix4x4/D3DMATRIX casts with proper transpose conversion

[bobtista]

• Closes Properly implement transpose between Matrix4 and D3DMatrix #552

Summary

Replaces all C-style casts between Matrix4x4/Matrix3D and D3DXMATRIX/D3DMATRIX with proper conversion functions that handle the row-major/column-major transpose.

Before:

DX8CALL(SetTransform(transform, (D3DMATRIX*)&m));

After:

D3DXMATRIX d3dMat = Build_D3DXMATRIX(m);
DX8CALL(SetTransform(transform, &d3dMat));
