Fix tvOS build (#3180)

## Description

After adding `stylusData` support, builds on `tvOS` fail. This PR fixes that

## Test plan

Add Gesture Handler to tvOS app (for example run `npx @react-native-community/cli@latest init TVTest --template @react-native-tvos/template-tv`) and check that it builds correctly.
