Improve Zendesk Tracks events

[frosty]

It seems as though our Tracks events for the WP Android Zendesk integration don't have parity with the events we send on iOS.

The full set of events covered on iOS that I don't think are used on Android are:

support_help_center_user_searched
support_help_center_viewed
support_new_request_viewed
support_ticket_list_viewed
support_new_request_created
support_new_request_failed
support_new_request_file_attached
support_new_request_file_attachment_failed
support_ticket_user_replied
support_ticket_user_reply_failed
support_ticket_list_view_failed
support_ticket_user_viewed
support_ticket_view_failed

Most of these are implemented by listening to a notification coming from the Zendesk SDK, which you can see here: https://github.com/wordpress-mobile/WordPress-iOS/blob/develop/WordPress/Classes/Utility/ZendeskUtils.swift#L885

We should try and ensure both platforms are sending the same events for the same situations.

I'm reopening this issue since some of the events cannot be tracked with the current version of the Zendesk library on Android. We can come back to it once it supports the same hooks as the iOS library.
