Provide a properly-typed ExpectedSizeForVersion() for types that need it

Provide a properly-typed ExpectedSizeForVersion() for types that need it

Rather than declaring ExpectedSizeForVersion() for all process_types
types and providing a default NOTREACHED() implementation, this only
declares it for process_types that request it by stating
PROCESS_TYPE_STRUCT_VERSIONED() in their proctype definition. This also
allows the argument to have the correct type, matching the type of the
struct’s version field.
