vim-patch:8.2.{1949,2781} (#22451)

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.

https://github.com/vim/vim/commit/b7c21afef14bba0208f2c40d47c050a004eb2f34

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)

https://github.com/vim/vim/commit/348be7ed07d164970ec0004bc278e254eb0cf5bf

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