Dylan Reid cc2e528c88 block: Avoid raw iovecs in VHDX sync I/O ...

The VHDX synchronous async I/O backend still converted owned
AsyncIoOperation targets back into raw iovec slices before calling the
VHDX read and write helpers. That kept pointer dereferences in the owned
path and allowed a backend mistake to violate the safety boundary.

Handle owned VHDX reads and writes through AsyncIoOperation copy helpers
instead. The VHDX file operations still run synchronously, but data is
copied through operation-owned buffers or guest-memory targets without
reconstructing Rust slices from raw iovec pointers.
