Dylan Reid 491f4e3343 block: Add owned VHDX sync I/O path ...

Refactor VhdxSync around shared iovec helpers which are marked unsafe.
Use these to implement safe wrappers for the new AsyncIo trait.

Leave the existing, unsound read/write vectored calls in place until
all callers are converted to the new interface later in this series.

In addition VHDX code assume it's safe to create slices to GuestMemory
via the AsyncAdaptor in existing code and explicitly after this
change. This is technically unsound as it can easily create multiple
mut refs. At least this is 'llvm update breaks the code' UB, not guest
exploitable UB...
