Fix TouchableOpacity componentDidUpdate causing an excessive number o…

…f pending callbacks (#35387)

Summary:
The commit 3eddc9a included on v0.69 introduced a wrong `if` statement inside the `componentDidUpdate` function of the `TouchableOpacity` component. As this `if` statement always evaluates to `true` (`(true || false) !== undefined`) we end up making unnecessary calls to the `_opacityInactive` method every time the component props changes, e.g. every time a `<Text>` inside the TouchableOpacity changes we call this function over and over, and this has been causing some performance issues on big lists.

This PR fixes this problem by adjusting the `componentDidUpdate` function to only call  `_opacityInactive` when necessary.

Closes #34442
Closes #32476
