Kyle Edwards b5f8113ca7 Genex: Add policy to handle empty list items in $<IN_LIST:...>

The old behavior of $<IN_LIST:...> is inconsistent with that of
if(IN_LIST), in that it does not find an empty search item even if
the list contains empty items. This change adds a new policy to
correctly handle empty items and make the behavior more consistent
with if(IN_LIST).

Fixes: #18556
