This change unifies the locals, stack, and globals objects exposed for WebAssembly frames via the Scope view and via DebugEvaluate to use the same underlying objects (implemented via interceptors). This also means that for locals and globals we now consistently expose names prefixed by a dollar symbol everywhere. Drive-by-fix: Move the debug::ScopeIterator implementation for WasmFrame into debug-wasm-support.cc, so WebAssembly scope details are all found in one place instead of scattered around the code. Drive-by-cleanup: Rename GetJSDebugProxy to GetWasmDebugProxy for consistency. GetJSDebugProxy is a bit misleading, since the debug proxy is not about JavaScript, but just exposed to JavaScript.
