wined3d: Allow using a different internal format for fbos.

OpenGL drivers do not support some low precision internal formats like GL_RGB5 for fbo color targets. Direct3D application depend on them, so provide a fallback format for render targets if the requested format itself is not supported.

wined3d: Allow using a different internal format for fbos.
