The default code generation model for Embedded Swift is "inlinable". DeferredCodeGen made the default code generation model "implementation", and there was no spelling for "interface". Introduce the experimental feature CodeGenerationModel=<model>, which can be any of those three options. The default remains "inlinable", but one can now specify "implementation" (which keeps most everything in SIL) or "interface" (which only keeps the generic things in SIL). The "interface" mode is more like non-embedded Swift for non-generic declarations, emitting them into the IR (only) but not SIL. Generic declarations would remain in SIL. Implements rdar://172433062.
