feat(core)!: Always use session from isolation scope

[mydea]

This PR ensures that we always take the session from the isolation scope, never from the current scope.

This has the implication that we need to be sure to pass the isolation scope to _processEvent, as this is where the session may be marked as errored. For this, I updated the internal method _processEvent to take the isolation scope as last argument, as well as streamlining this slightly.

I opted to update the signature of the protected _prepareEvent method too, and make currentScope/isolationScope required there. We already always pass this in now, so it safes a few bytes to avoid the fallback everywhere. This should not really affect users unless they overwrite the _processEvent method, which is internal/private anyhow, so IMHO this should be fine. I added a small note to the migration guide anyhow!
