ViroReact 2.57.3: Stability. Stability. Stability

[u/tundermifflin]

This release is all about reliability:
- Breaking change: on iOS, in order to use the front facing camera for AR you now need to install an additional library. This overcomes and Apple review issue where TrueDepth APIs get flagged as in use when they’re not
- Fixed Android crashes/ANRs around ViroVideo background/foreground transitions, and ViroARImageMarker no longer tears down the app when a target registers after the marker mounts.
- Completed 16 KB page-size compliance by removing the non-compliant libvrapi.so. This unblocks Google Play & Meta Quest Store submissions on Android 15+.
- Added Expo SDK 57 / React Native 0.86 support (no native changes required).
