Fabric: Change in a JS view's accessibilityValue prop does not fire the appropriate UIA update event

[jonthysell]

Problem Description

In PR #12287, support for the accessbilityValue prop was added. However it seems like only the TextInput actually files an event (when the text changes). However other custom views which set (and change) that property won't fire an event to notify UIA.

I.e. ComponentBaseComponentView should have something like this in updateAccessibilityProps:

winrt::Microsoft::ReactNative::implementation::UpdateUiaProperty(
      m_uiaProvider, UIA_ValueValuePropertyId, oldViewProps.accessibilityValue.text, newViewProps.accessibilityValue.text);
