Refactoring InterfaceDescriptors away from code-stubs.h

Refactoring InterfaceDescriptors away from code-stubs.h

code stub interface descriptor. The former is just concerned with how to call,
but the latter has many extra hints related to code generation and
deoptimization for the implementation of a particular code stub.
