RFR: 8348556: Inlining fails earlier for MemorySegment::reinterpret [v5]

[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 (notably `j.l.Object`) which, if implemented, can take us four additional levels of inlining. However, 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. 
> 
> So, we should discuss which of the proposed changes (if any), we'd like to integrate.
> 
> Tested and passed tier1-3
