Subject: [PATCH] Allow extending UIViewOperationQueue

Summary: public I need to extend NativeViewHierarchyManager to support a richer set of operations on Views, and those operations needs to be ran in UI thread.
Existing UIViewOperationQueue doesn't know about those operations, so I need to extend it too to allow them. This patch is making the class constructor protected to allow subclassing it from another package. Should not have any functional changes.
