Fail install if split is missing

An application can declare that it must be installed with at least
one split using the manifest attribute "android:isSplitRequired".
Setting the attribute to 'true' [default is 'false'], the application
can't be installed with a base-only. It must be accompanied by at
least one split [either feature or config].
