Description:
Replacing the Autofill background access check pixel with new protected data check pixel to reduce noise from false positives

Steps to test this PR:

1. In AppDelegate add this code to application(_:performFetchWithCompletionHandler):
   let manager = SecureVaultManager(includePartialAccountMatches: true, tld: AppDependencyProvider.shared.storageCache.tld) mainViewController?.currentTab?.secureVaultManagerIsEnabledStatus(manager, forType: .password)
2. Testing on device, run up the app and visit any website
3. Check that pixel m_secure-vault_is-enabled-checked_when-enabled-and-data-protected does not fire while the site is loading
4. Lock the phone screen and wait a few seconds
5. Via XCode Debug menu, simulate a background fetch which will trigger the code in step 1.
6. Confirm that when there is no access to protected data, the new pixel is fired
