Move virtio_gpu_resource_id_{get,put} to virtgpu_object.c and make them
static. Allocate and free the id on creation and destroy, drop all
other calls. That way objects have a valid handle for the whole
lifetime of the object.
Also fixes ids leaking. Worst offender are dumb buffers, and I think
some error paths too.
