Setting should handle android.settings.SYNC_SETTINGS from managed profile

When android.settings.SYNC_SETTINGS is fired from a managed profile, Settings
should handle it properly and displays the UI to manage accounts in the profile.
Since Settings uses a unified page to display both personal and work accounts,
it should redirect the intent to the UserAndAccountDashboardActivity in user 0

Bug: 79561138
Test: adb shell am start -a android.settings.SYNC_SETTINGS --user 10
      verifies the UI is showing work accounts
