fix(metro-config): Exclude `beforeAssetSerializationPlugins.preModule…

…s` from `stableChunkSource` (expo#33344)

# Why

<!--
Please describe the motivation for this PR, and link to relevant GitHub
issues, forums posts, or feature requests.
-->

Sentry user reported issue with using bundle splitting and
`beforeAssetSerializationPlugins` (used by Sentry Expo Metro Plugin).
The issue is the `stableChunkSource` becomes unstable due to updated
`premodules` by the `beforeAssetSerializationPlugins`

getsentry/sentry-react-native#4317

# How

<!--
How did you build this feature or fix this bug and why?
-->

This PR ensures the updated `premodules` are not affecting the chunk
global `premodules` but only the serialized output.

# Test Plan

<!--
Please describe how you tested this change and how a reviewer could
reproduce your test, especially if this PR does not include automated
tests! If possible, please also provide terminal output and/or
screenshots demonstrating your test/reproduction.
-->

I've added multiple scenarios to the tests to ensure this regression is
avoided in the future.

I also tried running the fix with
https://github.com/getsentry/sentry-react-native/tree/main/samples/expo
and the Web Release build is working with the fix. (Debug is not
affected, as premodules are changed only for release.)
