[WebIDL] Add support for converting dictionaries to JS

[WebIDL] Add support for converting dictionaries to JS
https://bugs.webkit.org/show_bug.cgi?id=165367

Patch by Sam Weinig <sam@webkit.org> on 2016-12-06
Reviewed by Darin Adler and Alex Christensen.

Source/WebCore:

- Adds support for converting dictionary types to JSValues via JSDOMConvert.
- Adopts that functionality to correct the CryptoKeyPair implementation, which
  is supposed to be a dictionary.
  (While doing this, I also update places that were passing both a CryptoKey
  and CryptoKeyPair to use a Variant, since they always only wanted one.)
- Re-works DOMPromise and DeferredPromise to be based on JSDOMConvert and IDLTypes.

Update to use new IDLType based promises.

* bindings/generic/IDLTypes.h:
Add a new type, ParameterType, to use as the parameter to
DOMPromise/DeferredPromise.

* bindings/js/JSCryptoKeyPairCustom.cpp:
Removed.

* bindings/js/JSDOMConvert.h:
(WebCore::JSConverter<IDLDictionary<T>>::convert):
Add JSConverter specialization for IDLDictionary. Have it simply forward to a generated
convertDictionaryToJS function, following the convention set in place by IDLEnumeration.

* bindings/js/JSDOMPromise.cpp:
* bindings/js/JSDOMPromise.h:
Re-write to be based on IDLTypes and JSDOMConvert, simplifying the implementation.

Update for variant based KeyOrKeyPair.

* bindings/scripts/CodeGeneratorJS.pm:
(GenerateDictionaryHeaderContent):
(GenerateDictionaryImplementationContent):
Add generation of the convertDictionaryToJS function. I made it require the JSGenerateToJSObject
extended attribute for now, as the majority of dictionaries do not need this code generated for them.

* bindings/scripts/test/JS/JSTestObj.cpp:
(WebCore::convertDictionaryToJS):
* bindings/scripts/test/JS/JSTestObj.h:
* bindings/scripts/test/TestObj.idl:
Add JSGenerateToJSObject to a dictionary to test generation in bindings tests.

Change KeyOrKeyPairCallback to take a Variant<RefPtr<CryptoKey>, CryptoKeyPair>, rather
than two separate arguments.

Removed.

* crypto/CryptoKeyPair.h:
Convert to a struct.

* crypto/CryptoKeyPair.idl:
Convert to a dictionary.
