Fix TextInput state revisions retaining their predecessor on Android

Summary:
#55719 added shadowViewFromShadowNode() to BaseTextInputShadowNode.h,
nulling props/state on a fragment's parentShadowView so a text-input
state revision does not retain the previous one.

AndroidTextInputShadowNode is `final : public ConcreteViewShadowNode<...>`
and builds its own fragment for the input's text value, so it never
received that fix. ShadowView::state points at the AndroidTextInputState
held when the fragment was built, and that fragment is stored into the
next state by updateStateIfNeeded(), making revision N retain N-1. The
chain grows one link per update and is destroyed by nested recursion,
exhausting the native stack.

Nothing reads Fragment::parentShadowView.props or .state - only tag,
layoutMetrics and componentHandle are consumed - so clearing them is
behaviour-preserving, including on the MapBuffer measurement path.
