 - Reason: Fixes an Android-specific issue (reproducible on certain Samsung models) where `onPress` events do not trigger for `Pressable` components when used inside a `Tooltip`. The root cause is that in the new architecture, `Pressability.measure()` reads stale layout information from the shadow tree instead of the actual native view hierarchy. This patch introduces a new `measureAsyncOnUI` method that measures the view asynchronously using the native layout hierarchy on the UI thread, bypassing stale shadow tree data.

+- Reason: Fixes a Fabric regression where VoiceOver on iOS only announces "expanded" but never "collapsed" for elements with `accessibilityState.expanded`. In `RCTViewComponentView.mm`, the code uses `value_or(false)` which skips the announcement entirely when `expanded` is `false`. This patch changes the logic to use `has_value()` and correctly announce both "expanded" and "collapsed" states, matching the old architecture (Paper) behavior.
