fix(eval)!: make Lua Funcref work as method and in substitute() (#20217)

Browse Source 
BREAKING CHANGE: When using a Funcref converted from a Lua function as
a method in Vim script, the result of the base expression is now passed
as the first argument instead of being ignored.

vim-patch:8.2.5117: crash when calling a Lua callback from a :def function

Problem:    Crash when calling a Lua callback from a :def function. (Bohdan
            Makohin)
Solution:   Handle FC_CFUNC in call_user_func_check(). (closes vim/vim#10587)
