Settings: Hide Development settings when it is turned off

This commit hides the Development and Performance settings items
when the user turns off Development settings. This sets things back
to tapping x number of times on the build number to once again enable
developer settings

Settings: Make Perf settings act just like dev setting - start hidden

The Performance settings should not show until the owner of the
device enables development options, guest users should not be able
to turn it on.

Settings : Fix accessibility shortcut

Shortcuts like accessibility, have preferences with titleText rather than
titleRes as their title. Settings only had a override for titleText, which caused
preference screens inside accessibility to not work. This commit addresses that.

Reproducable via :

1. Create a settings accessibility shortcut.
2. Launch shortcut and try to open an of the services

Expected behaviour : Appropriate ToggleAccessibilityServicePreferenceFragment should open
Observed behaviour : Same Settings instead gets relaunched instead
