fix: remove D3D11 debug layer flag that prevented startup on user machines

Browse Source 
DRAGONX_DEBUG was defined unconditionally, causing D3D11CreateDevice() to
request the debug layer via D3D11_CREATE_DEVICE_DEBUG. This layer is only
available on machines with the Windows SDK or Graphics Tools installed,
so the call fails with DXGI_ERROR_SDK_COMPONENT_MISSING on regular user
machines — causing the app to silently exit.
