Administration: Prevent repeat emails for identical plugin or theme auto-update attempt failures.

Browse Source 
This change adds a throttle mechanism to plugin and theme auto-update failure emails using similar logic to the email sent for a Core auto-update.

The first time a plugin or theme auto-update fails, the package and `new_version` will be tracked in the `auto_plugin_theme_update_emails` option. An email for this specific update attempt will not be resent.

However, if this update fails again and non-repeat failures or successful updates are also present, then the failure information will be included in that email (an email needs to be sent for the new events regardless).

Fixes #50448.
