RFR: 8329150: Remove CDS support for LatestMethodCache [v2]

[Ioi Lam]

> The CDS support for LatestMethodCache has no meaningful performance benefit. I am removing it for simplcity.
> 
> I also cleaned up the code a bit
> - No need to put LatestMethodCache in universe.hpp.
> - No need to use TRAPS in the init function
> - No need to malloc the LatestMethodCache objects

Ioi Lam has updated the pull request incrementally with two additional commits since the last revision:

 - Move definitions of _finalizer_register_cache close to the declaration of LatestMethodCache
 - @coleenp comments - no need to expose LatestMethodCache in universe.hpp
