** Class:  NonVersionableAttribute
**
**
** The [NonVersionable] attribute is applied to indicate that the implementation 
** of a particular member or layout of a struct cannot be changed for given platform in incompatible way.
** This allows cross-module inlining of methods and data structures whose implementation 
** is never changed in ReadyToRun native images. Any changes to such members or types would be 
** breaking changes for ReadyToRun.
