[QEMU PATCH v5 06/13] virtio-gpu: Support context init feature with virglrenderer

[Huang Rui <ray.huang@xxxxxxx>]

Patch "virtio-gpu: CONTEXT_INIT feature" has added the context_init
feature flags.
We would like to enable the feature with virglrenderer, so add to create
virgl renderer context with flags using context_id when valid.

V4 -> V5:
    - Inverted patch 5 and 6 because we should configure
      HAVE_VIRGL_CONTEXT_INIT firstly. (Philippe)
