MIPS: Refactoring InterfaceDescriptors away from code-stubs.h - external.

Port r23515 (fe0bdbf)

Original commit message:
Clean up and create seperation between the concept of a call descriptor and a
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.
