… with upstream defaults (#46221)

## Why

When we're building REA and RNWorklets we're missing some flag default
values. This came up here:

#Fixes #46209

## How

Added default values for flags in precompile config:

RNWorklets:
- `FETCH_PREVIEW_ENABLED` = false

REA:
- `USE_SYNCHRONIZABLE_FOR_MUTABLES` = true
- `USE_COMMIT_HOOK_ONLY_FOR_REACT_COMMITS` = true
- `FORCE_REACT_RENDER_FOR_SETTLED_ANIMATIONS` = true

Also verified that SDK-55 isn't affected by this issue since it has
other versions of these libs.

## Test-plan

✅ Prebuild REA and RNWorklets with new flags.

# Checklist

- [x] I added a `changelog.md` entry and rebuilt the package sources
according to [this short
guide](https://github.com/expo/expo/blob/main/CONTRIBUTING.md#-before-submitting)
- [x] This diff will work correctly for `npx expo prebuild` & EAS Build
(eg: updated a module plugin).
