dart:dom IDBObjectStore put should allow for any object to be used as key

[sethladd]

The put() method is defined at: http://www.w3.org/TR/IndexedDB/#widl-IDBObjectStoreSync-put-any-any-value-any-key

The key is of type "any" (further specified to be an Array, Date, DOMString, float) : http://www.w3.org/TR/IndexedDB/#dfn-valid-key

Our IDBObjectStore.dart in dom/generated/src/frog has this:

_IDBRequestJs put(Dynamic value, [_IDBKeyJs key = null]) native;

And when using code like this:

dom.IDBRequest addRequest = objectStore.put(msg, new Date.now().value);

The editor rightly complains that "int is not assignable to IDBKey"

The interface

  IDBRequest put(/SerializedScriptValue/ value, [/IDBKey/ key]);

and implementation

  _IDBRequestImpl put(value, [key = _default]) {

are now generated with type Dynamic.
