User exceptions are not signalled during DiscardLocalChangesStrategy callbacks on Kotlin native

[clementetb]

We are not able to properly handle user exceptions during the DiscardLocalChangesStrategy.onBeforeReset() and `DiscardLocalChangesStrategy.onAfterReset()' on mac os.

We need a way to properly signal core that an exception has ocurred.

The sync thread would crash in this situation. A work around would be to handle the exception manually on those callbacks.

This issue was blocked by https://github.com/realm/realm-core/pull/5564 but it was merged so it should be ready to work.
