[QEMU PATCH v4 05/13] virtio-gpu: Support context init feature with virglrenderer

[Huang Rui <ray.huang@amd.com>]

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.
