Configuration option to stop/disable post-crash replay recording on Android

### Problem Statement

Currently, when an error/crash occurs, the SDK samples the event and continues recording post-crash replay until the session naturally ends. This replay is absolutely useless for us. I need a purely configuration-based way to completely prevent or instantly cut off replay recording right after a crash event occurs.

### Solution Brainstorm

I would like a new configuration option in SentryReplayOptions (or a built-in behavior within beforeErrorSampling) that automatically stops the replay recorder immediately after a crash event is captured.

For example, a flag like `stopRecordingOnCrash`:
```kotlin
SentryAndroid.init(context) { options ->
options.sessionReplay.onErrorSampleRate = 1.0
// Proposed flag to cut off recording instantly after a crash/unhandled exception
options.sessionReplay.isStopRecordingOnCrash = true

options.sessionReplay.beforeErrorSampling =
SentryReplayOptions.BeforeErrorSamplingCallback { event, hint ->
event.isCrashed // Only capture replays for crashes
}
}
```

從 SentryReplayOptions 和 beforeErrorSampling callback 開始，接著追蹤 Android 當機事件如何與 session replay 錄製互動。定義設定行為，讓 replay 在擷取到當機後立即停止，並確認一般 replay 和錯誤取樣不受影響。
