The new implementation also adds some extra error checking to catch

This CL adds a crate `sync` containing a type sync::Mutex which wraps
the standard library Mutex and mirrors the same methods, except that
they panic where the standard library would return a PoisonError. This
API codifies our error handling strategy around poisoned mutexes in
crosvm.
- Crosvm releases are built with panic=abort so poisoning never occurs.
A panic while a mutex is held (or ever) takes down the entire process.
Thus we would like for code not to have to consider the possibility of
poison.
- We could ask developers to always write `.lock().unwrap()` on a
standard library mutex. However, we would like to stigmatize the use
of unwrap. It is confusing to permit unwrap but only on mutex lock
results. During code review it may not always be obvious whether a
particular unwrap is unwrapping a mutex lock result or a different
error that should be handled in a more principled way.
Developers should feel free to use sync::Mutex anywhere in crosvm that
they would otherwise be using std::sync::Mutex.

break up mmio device creation and registration
Moving forward registration will be handled by the architecture specific
code. However, creation will be handled by the common code. To make that
easier split up the two steps so a list of devices is created, then each
is registered later.
Start moving to a model where the configuration generates a set of
components that are passed to the architecture. The architecture will
crate a VM from the components.
Break up the big run_config function and move architecture specific
parts to the various architectures.
This doesn't refactor the function calls each architecture makes, but
moves the setup flow in to the arch impls so that they can diverge in
