Remove dead updateLayout JS→native bridge path

Now that both platforms observe content height natively (iOS via KVO,
Android via OnLayoutChangeListener), the JS-callable updateLayout()
is unused. Remove:

- updateLayout() and prevLayoutDetentIdentifier from iOS SheetView
- AsyncFunction("updateLayout") from both platform module definitions
- updateLayout method from the JS BottomSheetNativeComponent

Android's updateLayout() is kept as a private implementation detail
since the keyboard insets listener and native layout observer both
call it internally.
