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
}
}
```

Start with SentryReplayOptions and the beforeErrorSampling callback, then trace how Android crash events interact with session replay recording. Define the configuration behavior so replay stops immediately after a captured crash, and verify that normal replay and error sampling remain unaffected.
