vim-patch:8.2.2781: add() silently skips when adding to null list or blob
Problem: Add() silently skips when adding to null list or blob.
Solution: Give an error in Vim9 script. Allocate blob when it is NULL like
with list and dict.

Do not implicitly change a NULL blob/dict/list to an empty one.
N/A patches for version.c:
vim-patch:8.2.1949: Vim9: using extend() on null dict is silently ignored
Problem: Vim9: using extend() on null dict is silently ignored.
Solution: Give an error message. Initialize a dict variable with an empty
dictionary. (closes vim/vim#7251)

N/A because Nvim's current behavior is an error message as a locked
list/dict, which is more consistent. Ref #4615.
