When a tab is in the background, all RemoteAccessibles in that tab (including the descendants of any iframes) should get the offscreen state. We already handle this for LocalAccessibles.

Note that it's important to distinguish between focused and foreground/active here. A tab that isn't focused might still be in the foreground; e.g. if focus is in the address bar while a tab is still visible.

BrowsingContext::IsActive might be useful, though I'm not sure whether that propagates up/down the BrowsingContext tree for iframes. Looking at the code briefly, it does seem to walk ancestors, which is promising.

Practical impact: When CTW is enabled, live regions in background tabs are reported by NVDA when they shouldn't be.
