patch 8.2.0154: reallocating the list of scripts is inefficient
Problem: Reallocating the list of scripts is inefficient.
Solution: Instead of using a growarray of scriptitem_T, store pointers and
allocate each scriptitem_T separately. Also avoids that the
growarray pointers change when sourcing a new script.
