For #25034 fix disabled redirectToAppPermissionsSystemSettingsTest UI test ✅ successfully passed 100x on Firebase

Summary:
• Moved the test from SmokeTest to SettingsPrivacyTest to avoid the retryRule
• Refactored assertBlockedByAndroid and assertUnblockedByAndroid (switched to UIAutomator from Espresso because from time to time was unreliable)
• While performing the test runs noticed some timing issues when performing the lots of pressBack actions so I've fixed that as well

Flaky on the last run, will check what's going on.

Looks like in some cases the "Blocked by Android" remained displayed for "Location" even though the system permission was granted.

Added verifySystemGrantedPermission to be sure that all system permissions are granted and everything is in sync when doing the assertion in Fenix.
