fix(vsock): remove dead virtio_dump debug helper

Delete the unused virtio_dump module and stop exporting it from the
vsock crate. The file contained a large debug-only PCI/MMIO dump helper
that was compiled as dead code and was no longer referenced anywhere in
the tree.

Removing it drops an unmaintained code path that parsed host-controlled
virtio PCI capability state without participating in the shipping vsock
data path, reducing attack surface and keeping the crate aligned with
the actual runtime implementation.
