Moved the compilation/instantiation pipeline to work off the module object (JSObject), making the compiled module data (the FixedArray) an implementation detail. This: - simplifies the code by removing duplicate decode->compile->instantiate sequences - sets up the stage for "dressing up" the runtime model with stronger typed APIs - helps relanding this CL: https://codereview.chromium.org/2305903002/. It turns out that GCs during the cloning/instantiation events cause trouble, and centering the source of truth on the module object helps address this issue. In the process, clarified cctest setup for wasm-capable isolates, and changed signatures for consistency (using ModuleOrigin througout).
