feat: live preview: added outside iframe code

[contentstackMridul]

This pull request introduces a new ON_RELOAD event to the live preview system, enabling enhanced functionality for handling reload scenarios. The changes span multiple files, adding support for the new event and ensuring proper integration into the live preview event manager and hooks.

Addition of ON_RELOAD event:

• Constant definition: Added ON_RELOAD to the LIVE_PREVIEW_POST_MESSAGE_EVENTS object in src/livePreview/eventManager/livePreviewEventManager.constant.ts.
• Event handling: Updated the EventManager initialization in src/livePreview/eventManager/livePreviewEventManager.ts to dynamically set the target based on the presence of window.opener.

Integration into hooks:

• New hook: Created useOnReloadPostMessageEvent in src/livePreview/eventManager/postMessageEvent.hooks.ts to listen for the ON_RELOAD event and reload the page with updated parameters.
• Hook usage: Integrated useOnReloadPostMessageEvent into the initialization flow in sendInitializeLivePreviewPostMessageEvent.

Type definition:

• Event data type: Added OnReloadLivePreviewPostMessageEventData interface in src/livePreview/eventManager/types/livePreviewPostMessageEvent.type.ts to define the structure of the ON_RELOAD event payload.
