This is the final change list in the list of refactorings to split off the implementations of v8::StackFrame and CallSite objects (as used by the V8 JavaScript stack API). See https://bit.ly/v8-stack-frame for the whole story. This CL adds the v8::internal::StackFrameInfo class as new backing implementation of v8::StackFrame, and puts it into debug-objects.tq to indicate that it's used for the debugger API only. This new class is lightweight and only holds on to static information about the stack frame, and is thus usable for the V8 inspector to implement async stack traces in a cheaper manner going forward.
