Fix build break in MSVC (facebook#26462)

Summary:
Merging react-native-windows to 0.60 - the visual studio compiler seems to take issue with the existing code

## Changelog

[Internal] [Fixed] - Build fix for react-native-windows (MSVC)
Pull Request resolved: facebook#26462

Test Plan:
No real change, just making compilers happy.

### Side Note
We'll want this change cherry-pickered to RN 0.60 and RN 0.61 so users of react-native-windows dont have to use our fork of react-native.
