The "imports" and "exports" that were exposed on WebAssembly frames via
Debug-Evaluate aren't useful for the DWARF C/C++ extension (and likely
not for any other language extension), since they only expose static
information that's easily available (upfront) by reading the Wasm wire
bytes.
In fact, there are already standardized functions in the WebAssembly
specification, namely `WebAssembly.Module.imports(module)` and
`WebAssembly.Module.exports(module)`, which yield static information
about the imports and exports of a Wasm module.
So instead of exposing special, non-standard "imports" and "exports", we
now instead expose both the "instance" and the "module" objects via both
the Debug Proxy and the Scope view, and also add internal [[Exports]]
and [[Imports]] properties to WasmModuleObject, which under the hood use
the standard methods mentioned above.
