RFR: 8348556: Inlining fails earlier for MemorySegment::reinterpret [v7]

[Per Minborg]

> This PR proposes to add some `@ForceInline` annotations in the `Module` class in order to assist inlining of FFM var/method handles.
> 
> There are also some changes in other classes which, if implemented, can take us three additional levels of inlining. I drew a line there. There is a tradeoff with adding `@ForceInline` and just trying to get as deep as possible for a specific use case is probably not the best idea. 
> 
> Updating the `j.l.Object` constructor is crucial for the higher depths.
> 
> Tested and passed tier1-3
