[Bug] Fix VoiceOver for SegmentedControl

[oddballdave]

Description of Change

On iOS, the SegmentedControl did not correctly announce the state or the role of each tab contained within it. After extensive research, this looks to be an issue with either React Native and/or iOS itself. To mitigate the problem the SegmentedControl was modified to supply the text that VoiceOver should speak. Note that this is not an issue on Android.
