Supplement the implementation of API Pull for the Settings page

[eason9487]

Changes proposed in this Pull Request:

This is a preliminary change before granting API Pull access is added to the onboarding flow.

To avoid too many file changes for subsequent PRs, this PR changes a few things first:

• Remove the unused prop hideNotificationService from MerchantCenterAccountInfoCard.
  • The use of hideNotificationService has been removed by PR #2639
• Add the two missing properties to the GoogleMCAccount type.
• Stay with the loading state of EnableNewProductSyncButton during the page redirection.
• Adjust two event tracking and add their doc.
  • gla_enable_product_sync_click: Add the page event property to indicate which page the event happened to facilitate further breakdown after the onboarding page also triggers this tracking in a later PR.
  • gla_disable_product_sync_click: Change its trigger time to when the confirm button in the confirmation modal is clicked rather than when the button to open the confirmation modal is clicked.

Detailed test instructions:

1. Open the Console tab in the browser DevTool
   • Configure it as below
     
   • Run localStorage.setItem( 'debug', 'wc-admin:*' ) to enable tracking debugging mode
2. Go to the Settings page.
3. Check if the functions to enable and disable the new product sync (API Pull) work well as before
4. View the Console tab in the browser DevTool and check if the following event tracking is triggered
