feat(eval/method): partially port v8.1.1996

Problem:    More functions can be used as methods.
Solution:   Make various functions usable as a method.

Partial port as this does not include eval.txt change for listener_add.

Cherry-pick eval.txt changes for:
- bufadd from v8.1.1626:
  https://github.com/vim/vim/commit/5ca1ac373ae62b37152cb6f85916b402eda520a5
- setloclist and setqflist headers from:
  https://github.com/vim/vim/commit/b0d45e7f5354375edd02afafde3bd37dac1515ff

Correct eval.txt typo for settabwinvar method call (matches latest Vim).
