Allow to disable auto-start for replays

[mydea]

Related to #7192, it may make sense to add a config option like autoStart which can be set to false to disable auto-starting the replay.
This would simplify setups where users want to manually control replay recording.

Currently, you can accomplish the same through some other hoops:

replaysSessionSampleRate: 0, 
  replaysOnErrorSampleRate: 0,
  integrations: []
});

// Later when you want to start/stop replay, add the integration
client.addIntegration(new Replay());

However, this becomes tricky when users want to conditionally start/stop replays, as you need to always check if it was added yet etc.

thank you, agree with you, but so, need to create flow how we can start/stop without unexpected cases from Sentry SDK/worker because not looks like we have some bugs

[mydea]

If you have worker errors or similar, could you create a separate issue for this? This shouldn't be the case, and we should be catching these.

I created #7192
after stop/start I do not see in Network POST requests to Sentry server

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
