vim-patch:8.1.1911: more functions can be used as methods

Browse Source 
Problem:    More functions can be used as methods.
Solution:   Make a few more functions usable as a method.
64b4d73524

Note that the old-style version of Test_byteidx() was already translated
to a Lua test in 069_multibyte_formatting_spec.lua. Keep both versions,
using Test_byteidx() to mainly test the method call syntax for byteidx()
and byteidxcomp().
