[Android] call SplitCompat.installActivity on ContextUtils context

This CL aims to fix a bug with native resources not loading after a
locale override.

Currently, when an override language split is downloaded and applied
only Java resources load until Play Store daily hygiene runs and moves
the language split apks to `/data/app/` from `/data/data`.

To make resources available on a context SplitCompat.installActivity
should be called.

This CL calls SplitCompat.installActivity on the global application
context ContextUtils.  This context is used to load native resources in
ResourceBundle.getLocalePakResourcePath.
