1/2 TextInput accessibilityErrorMessage (Talkback, Android) (facebook…

…#33468) Summary: **Android**: The functionality consists of calling the [AccessibilityNodeInfo#setError][10] and [#setContentInvalid][13] method to display the error message in the TextInput. **Fixes [https://github.com/facebook/react-native/issues/30848][51] - Adding an accessibilityErrorMessage prop to the TextInput Component**: **Android**: The prop accessibilityErrorMessage triggers the AccessibilityNodeInfo method [setError][10] which automatically sets the correct properties on the AccessibilityNodeInfo that will inform screen readers of this state. The method calls setContentInvalid(true) and setError(youErrorString) on the AccessibilityNodeInfo. **Fixes [https://github.com/facebook/react-native/issues/30859][52] - Detecting changes in the Error state (text inputs)** **Fabric - Android** - Adding accessibilityErrorMessage to field AndroidTextInputState. ReactTextInputManager and ReactEditText receive state updates both from [Javascript][32] and [cpp (fabric)][34]. - accessibilityErrorMessage is added to the fabric AndroidTextInputState field - The updates are received in the ReactAndroid API with method updateState from ReactTextInputManager - After updating the TextInput text with onChangeText, the update of the accessibilityErrorMessage is triggered with method maybeSetAccessibilityError which triggers [setError][10]. More info: - An explanation of [state updates between fabric and ReactAndroid for the TextInput component][34] - [ReactNative renderer state updates][35] **Paper - Android** - Adding accessibilityErrorMessage to ReactTextInputShadowNode to trigger updates in Paper renderer when accessibilityErrorMessage is changed within the onChange callback.
