Should ClipboardItemData allow non-Promises?

This implies that the options argument only allows Promises of Blobs and strings, and the spec says so too; however, some browsers allow Blobs and strings to be used directly, and MDN seems to document that behavior too.

I think https://webidl.spec.whatwg.org/#es-promise means that conversion from ECMAScript value V to an IDL Promise<T> value effectively performs new Promise((resolve, reject) => resolve(V)).

So yes, non-Promises should be accepted.

It seems this is regressed at some point after #1102.

Lines 3644 to 3647 in fc5fe1a

	declare var ClipboardItem: {
	prototype: ClipboardItem;
	new(items: Record<string, string | Blob | PromiseLike<string | Blob>>, options?: ClipboardItemOptions): ClipboardItem;
	};

Well actually it's there, so maybe it's just that TS should import the latest bits?
