This changelist makes the GDB-stub actually execute GDB-remote commands, by accessing the Wasm engine state. More precisely: - class GdbServer registers DebugDelegates that receive debug notifications when a new Wasm module is loaded, when execution suspends at a breakpoint or for an unhandled exception. - Since the GDB-remote commands arrive on a separate thread, all queries from the debugger are transformed into Task objects, that are posted into a TaskRunner that runs in the Isolate thread. - class WasmModuleDebug contains the logic to retrieve the value of globals, locals, memory ranges from the Wasm engine and to add/remove breakpoints.
