Add touch filtering for Top Intro Preference

- Adds touch filtering for the Top Intro Preference. This makes
the preference not clickable when it's obscured by other windows.

HIGH_LEVEL_CL_EXPLANATION:
- Tapjacking is currently possible on the TopIntroPreference. Set android:filterTouchesWhenObscured to true to mitigate. (See: https://developer.android.com/privacy-and-security/risks/tapjacking)
