[lworld] RFR: 8367415: Fully encapsulate array allocation in oopFactory [v3]

[Coleen Phillimore]

> This makes oopFactory and deoptimization the only friends of private ArrayKlass::allocate_instance.  This is similar to the PR https://github.com/openjdk/jdk/pull/27372 in mainline with some extra handling for new_refArray (rather than calling RefArrayKlass::allocate_instance() directly.
> Tested with tier1-4.
