vulkan-cereal: plumb virtgpu ctx_id to process pipe
The virtio-gpu context ID is an unique identifier allocated by the
guest kernel, via idr_alloc(..). These IDs can be reused, but
virtio-gpu gurantees that re-use will only happens after a
particular context has been destroyed.
Many operations related to resource sharing between guest
processes, and between gfxstream and virtgpu are done in reference
to this context id.
gfxstream has a clear analogue to this already --> m_puid, which
is set via connecting to the "pipe:GLProcessPipe" service in the
guest.
The immediate goal is is make m_puid == ctx_id, so the guest
kernel can reference each host render thread via the ctx_id.
