Subject: [PATCH] CodeGenerators: Add support for LegacyNoInterfaceObject IDL
 attribute

When applied, corresponding interface object will not be exposed on the
global object, e.g. for the following IDL:
```
Exposed=(Window,Worker), LegacyNoInterfaceObject]
interface ANGLE_instanced_arrays {
};
```

executing `"ANGLE_instanced_arrays" in window` will return `false`.
