C++-ify ravenscar_arch_ops

This turns ravenscar_arch_ops into an abstract base class and updates
all the places where it is used.  This is an improvement because it
avoids any possibility of forgetting to set one of the function
pointers.  It also makes clear that these functions aren't intended to
be changed dynamically.

This version of the patch removes the prepare_to_store method, as it
is unused, and it is easy enough to add if it is ever needed.
