[foreign] RFR: cleanup Pointer API

[Sundararajan Athijegannathan]

* Runtime class could be final and package-private. All static helpers 
methods could be package-private as well - because HeaderImplGenerator 
in the same package creates method handles on those methods.

* Pointer.toString, .copy methods: "public" removed. Usually in APIs, we 
write "public" explicitly - even though interface methods are public by 
default, right?

+1 other than that.
