The installation of conditional features in WebAssembly needs
the context to be set in the isolate to fix
https://ci.chromium.org/ui/p/chromium/builders/try/linux-rel/b8851955177753045904/overview.
The context cannot be passed explicitly to all uses of the
context, because Isolate::object_function() accesses
the native_context through the isolate.
