Web Inspector: ObjC RWIProtocol codegen should better handle optional members

ObjC RWIProtocol codegen should better handle optional members

For example, Highlight Config has optional color values:

    "id": "HighlightConfig",
    "type": "object",
    "properties": [
        { "name": "showInfo", "type": "boolean", "optional": true, "description": "Whether the node info tooltip should be shown (default: false)." },
        { "name": "contentColor", "$ref": "RGBAColor", "optional": true, "description": "The content box highlight fill color (default: transparent)." },
        { "name": "paddingColor", "$ref": "RGBAColor", "optional": true, "description": "The padding highlight fill color (default: transparent)." },
        { "name": "borderColor", "$ref": "RGBAColor", "optional": true, "description": "The border highlight fill color (default: transparent)." },
        { "name": "marginColor", "$ref": "RGBAColor", "optional": true, "description": "The margin highlight fill color (default: transparent)." }
    ],

However we return without checking if it was null or not:

    - (RWIProtocolDOMRGBAColor *)contentColor
    {
        return [[RWIProtocolDOMRGBAColor alloc] initWithInspectorObject:[[super objectForKey:@"contentColor"] toInspectorObject].get()];
    }

Should be something like:

    - (RWIProtocolDOMRGBAColor *)contentColor
    {
        RWIProtocolJSONObject *object = [[super objectForKey:@"contentColor"];
        if (!object)
            return nil;
        return [[RWIProtocolDOMRGBAColor alloc] initWithInspectorObject:[object toInspectorObject].get()];
    }

This patch modifies the inspector protocol generator. Please ensure that you have rebaselined any generator test results (i.e., by running `Tools/Scripts/run-inspector-generator-tests --reset-results`)
