[D3D8] Add some depth/stencil buffer stuff

[Christian Costa]

Hi,

This patch makes Incoming Forces go further.
(and crash in vertex/pixel shaders stuff).

Bye.
Christian

Changelog :
Handle creation of a depth/stencil buffer when creating a device.
Implement IDirect3D8DeviceImpl_GetDepthStencilBuffer.
