8202907: Consolidate the design and implementation of the nicl support
Misc improvements to binder performance model:
* Reference class is rewritten so that all MH are now static
* turned LayoutType into an interface
* Avoid Scope.allocateStruct in NativeInvoker (as that causes layout parsing)
* pre-cache all static info about a call in NativeInvoker, UpcallHandler
