I was OOO last two days and back on this RFR.
It's okay to add this experimental API in java.util.Objects. We can
revisit if there is a better name (or no better method name) in the
future. It would be good for the javadoc to state that the returned
size is an implementation-specific approximation of the amount of
storage consumed by this object. The estimate may change in different
invocation of the JVM.
