This CL moves all methods related to scripts and eval origin (HasScript, GetScript, IsEval, GetEvalOrigin) from JSStackFrame to StackFrameBase, because it also applies to WasmFrames. This makes the AppendFileLocation method append the same information to WasmStackFrames and AsmJsWasmStackFrames than to JSStackFrames.
