Changes in v6:
- Remove the unstable API flags check because virglrenderer is already 1.0.
- Squash the render server flag support into "Initialize Venus".

I wonder if it's a good idea to initialize venus by default. It
doesn't seem to require vulkan during initialization, but this may
evolve. Make it optional?

I am fine. In fact, vulkan is widely used for graphic area such as gaming,
compute, VR/AR, etc.

Actually, making it optional is useful because Venus support is optional in
virglrenderer (= having VIRGL_RENDERER_VENUS defined doesn't mean that
Venus is supported).
