Karl Seguin a45f9cb810 Set v8::Signature on FunctionTemplates ...

This causes v8 to verify the receiver of a function, and prevents calling an
accessor or function with the wrong receiver, e.g.:

```
const g = Object.getOwnPropertyDescriptor(Window.prototype, 'document').get;
g.call(null);
```

A few other cleanups in this commit:
1 - Define any accessor with a getter as ReadOnly
2 - Ability to define an accessor with the DontDelete attribute
    (window.document and window.location)
3 - Replace v8__ObjectTemplate__SetAccessorProperty__DEFAULTX overloads with
    new v8__ObjectTemplate__SetAccessorProperty__Config
4 - Remove unnecessary @constCast for FunctionTemplate which can be const
    everywhere.
