Fix setLayoutAnimationEnabled assigning variable to itself

[Nedunchezhiyan-M]

Summary

setLayoutAnimationEnabled() in LayoutAnimation.js assigns isLayoutAnimationEnabled back to itself instead of the value parameter:

// Before (bug)
function setLayoutAnimationEnabled(value: boolean) {
  isLayoutAnimationEnabled = isLayoutAnimationEnabled; // no-op
}

// After (fixed)
function setLayoutAnimationEnabled(value: boolean) {
  isLayoutAnimationEnabled = value;
}

This makes the function a complete no-op, meaning LayoutAnimation can never be toggled at runtime once initialized from the feature flag.

Changelog:

[GENERAL] [FIXED] - Fix setLayoutAnimationEnabled not applying the value parameter

Test Plan

1. Call LayoutAnimation.setLayoutAnimationEnabled(false) and verify layout animations are disabled
2. Call LayoutAnimation.setLayoutAnimationEnabled(true) and verify they re-enable
3. Previously both calls had no effect due to the self-assignment bug
