Issue TIMOB-18099: iOS: Parity: Clean up tab events
1. In Android we have the click event on the tab, but in iOS we do not. This event should be removed for Android as well, since it's confusing and quite useless as tabs can be selected by swipes. 2. In Android since 3.5.0 we have the tab selected and unselected events. In iOS we have focus/blur which fire exactly when the tab is selected and unselected. So iOS tab focus/blur should be renamed selected/unselected to match Android. 3. Tab focus/blur should be removed since we have selected/unselected which are much clearer, and since it makes no sense for tabs to be focused/blurred. Focus/blur events should occur on the Window or perhaps on the entire tab group, but not for "tabs" which are only used for selection and are not really a containing UI element. Note that for Android tab focus/blur fire in numerous cases, not just tab selection, and in all "relevant" cases we have Window focus/blur in any case so for tabs they're redundant.
