Spring CaffeineCache with LoadingCache

When CaffeineCache is created with a LoadingCache, the LoadingCache is used with the method public ValueWrapper get(Object key) but not with method public <T> T get(Object key, @Nullable Class<T> type). Using LoadingCache is incompatible with @Cacheable pattern but consistently call the LoadingCache in both methods is better than now. Removing the usage is a backward-incompatible change.

Closes gh-25173

@snicoll ... any chance to take this PR into consideration? (also close it is a possibility.. 😀)

Comment From: snicoll

It very much was @stefano-salmaso but I've been busy on other things lately. I apologize for the delay and I've flagged the original issue for the 5.3 bucket. I am not sure if we're going to fix it the way you've suggested so I'll keep both the issue and the PR open for now.

Thanks for the PR but I've decided to use a different approach, see https://github.com/spring-projects/spring-framework/commit/f3cedf268b3ef0c3ef14766db4e02d17346f8b24 for more details.
