drm/virtio: implement context init: allocate an array of fence contexts

Browse source

We don't want fences from different 3D contexts (virgl, gfxstream,
venus) to be on the same timeline.  With explicit context creation,
we can specify the number of ring each context wants.

Execbuffer can specify which ring to use.
