Remove injecting developer options into Settings itself

- It can improve performance because we use less injected item
- Also use RestrictedPreference instead just checking restrictions,
  so we follow policy transparency.

Note: Renamed DevelopmentSettingsDashboardActivity to
DevelopmentSettingsActivity,
because DevelopmentSettingsDashboardActivity could in disabled state
even after Settings upgrades, use a new name to prevent this issue.
