Avi Kivity af8ef54d5a managed_bytes: introduce with_linearized_managed_bytes() ...

A large managed_bytes blob can be scattered in lsa memory.  Usually this is
fine, but someone we want to examine it in place without copying it out, but
using contiguous iterators for efficiency.

For this use case, introduce with_linearized_managed_bytes(Func),
which runs a function in a "linearization context".  Within the linearization
context, reads of managed_bytes object will see temporarily linearized copies
instead of scattered data.
