vim-patch:8.1.2011: more functions can be used as methods

Problem:    More functions can be used as methods.
Solution:   Make various functions usable as a method.  Make the window
            command test faster.
ce90e36f59

test_* functions in the patch are N/A as they modify internal state.

Include test changes for test_ignore_error and test_feedinput (though they aren't run).
Other changed tests were excluded from previous patches, except test_termcodes.vim, which hasn't
been ported yet.
