SF: Update metadata of unvisible layers to backend

ARC++ relies on metadata to convey a variety of information, including
window states through a in-house metadata. Some of them may change when
a layer is invisible, and ARC++ backend needs to respond to these
changes immediately. Such case may happen when user minimizes a window.
