[build-properties] Add field to enable/disable privacy manifest aggre…

…gation (#28646)

# Why

There are a few issues right now with privacy manifest aggregation
(facebook/react-native#44410,
facebook/react-native#44402,
facebook/react-native#44402) that I expect will
be fixed in React Native 0.74.2, but in order to ensure that this
doesn't break builds I've disabled it by default and added this build
property to allow folks to toggle it on. We can switch on by default
when 0.74.2 is released and proven to handle some edge cases better.

# How

Same old process for adding a new property

# Test Plan

Run tests

# Checklist

- [x] Documentation is up to date to reflect these changes (eg:
https://docs.expo.dev and README.md).
- [x] Conforms with the [Documentation Writing Style
Guide](https://github.com/expo/expo/blob/main/guides/Expo%20Documentation%20Writing%20Style%20Guide.md)
- [x] This diff will work correctly for `npx expo prebuild` & EAS Build
(eg: updated a module plugin).
