LineageParts: Add an activity to show the Lineage platform logo

*) Launched by lineage-sdk LineageVersionPreference when triple-clicking
   LineageOS version field in About phone.

*) Easter egg code is retained (from AOSP original code) but disabled by
   commenting out the setOnLongClickListener() call.  We can reenable
   later when needed.
