Align with sentry-javascript on SentryClient hooks

### Description

The JS SDK provides multiple hooks that our SDK does not have -- e.g. `afterSendEvent`, etc. We should check for parity and align with them. This would also make some of our interfaces cleaner (e.g. ReplayController, which could subscribe for sent events instead of SentryClient calling this).

首先，將此 SDK 中的 SentryClient hooks 與 sentry-javascript 提供的 hooks 進行比較，包括 afterSendEvent。接著檢查 ReplayController 如何訂閱已傳送的事件；當相關 hooks 具備對等性，且受影響的介面不再需要所述的直接耦合時，即表示完成。
