Web Inspector: Network panel: Disable context menu items for incomple…

…te resources

https://bugs.webkit.org/show_bug.cgi?id=242035

Reviewed by Devin Rousso.

Information collected about resources loaded before Web Inspector was opened is missing most metadata,
like resource timing data, HTTP method, request headers, etc.

* Source/WebInspectorUI/UserInterface/Models/Resource.js:
(WI.Resource.prototype.get hasMetadata):

Add a new member to quickly check if the resource has metadata.

* Source/WebInspectorUI/UserInterface/Views/ContextMenuUtilities.js:

In absence of metadata, context menu items to copy as cURL, copy as fetch, copy HTTP request
and copy HTTP response should not be shown to avoid getting useless output.
