vim-patch:8.1.1933: the eval.c file is too big (#19462)

Problem:    The eval.c file is too big.
Solution:   Move code related to variables to evalvars.c. (Yegappan
            Lakshmanan, closes vim/vim#4868)
https://github.com/vim/vim/commit/0522ba0359c96a8c2a4fc8fca0d3b58e49dda759

Name the new file eval/vars.c instead.
