Subject: Use static filter for inflater of RemoteViews

This will get rid of the RemoteViews leak caused by ViewStub keeping
reference of LayoutInflater. But subclasses of RemoteViews won't be
affected to avoid breaking overriden usage.
Bug: 141699084
Test: Manually test. Leak disappeared. atest RemoteViewsTest
