Skip UIManager constants lookup on react-native-windows (#4591)

## Description

On `react-native-windows` with the new architecture,
`UIManager.getViewManagerConfig('getConstants')` in `createHandler.tsx`
logs a soft error from RN's `BridgelessUIManager`, because RNW does not
install the legacy UIManager constants binding. The error is raised
while the bundle is being evaluated, and RNW treats it as an instance
error, which leaves Release builds with a blank screen.

This PR skips the lookup on Windows. The lookup is a Paper-only
mechanism and never returned anything there, so nothing changes for the
other platforms.

Fixes #4587

## Test plan

Reporter verified the same change via patch-package on RNW 0.84 / RNGH
2.33.0, Release MSIX.
