Make named constructors' |prototype|s have the right property descriptor

As per https://heycam.github.io/webidl/#named-constructors, a named
constructors "prototype" property should NOT be writable, configurable or
enumerable, yet we were creating a property with the opposite
characteristics.

Call v8::Object::DefineOwnProperty() rather than v8::Object::Set() so we can
pass the property descriptor values we want.

More tests for named constructors are coming in
https://github.com/web-platform-tests/wpt/pull/14841

While here, do some minor cleanups suggested in the review:
* Rename |interfacePrototype| to |interface_prototype| to follow Chromium's
  coding style
* Replace an if check for |result| with a CHECK(), as we are already calling
  ToChecked() when setting it.
