ggml-virtgpu: improve the reliability of the code (#19846)

ggml-virtgpu-backend: validate the consistency of the received objects

This patch adds consistency checks in the ggml-virtgpu-backend (running on the host side) to ensure that the data received from the guest is consistent (valid pointers, valid sizes and offsets).

ggml-virtgpu-backend: add fallback/skips for optional ggml backend methods

  1. bck->iface.synchronize(bck)
  2. buft->iface.get_alloc_size(buft, op)
  3. buft->iface.get_max_size(buft)

these three methods are optional in the GGML interface. get_max_size was already properly defaulted, but backend sychronize and butf get_max_size would have segfaulted the backend if not implemented.
