Wasm frames can be either compiled or interpreted. For interpreted wasm frames, there is only one physical stack frame representing an arbitrary stack of interpreted functions. Hence the physical stack frame needs to provide a summary of the underlying functions. Summaries were tailored for JavaScript frames before. Now they are universal. The refactored FrameSummaries are now also used in the FrameInspector, and from the StackFrame objects themselves, to avoid code duplication. All dispatch is implemented "manually", making the FrameSummary still stack-allocatable.
