vim-patch:8.2.3619: cannot use a lambda for 'operatorfunc' (#19846)

Browse Source 
Problem:    Cannot use a lambda for 'operatorfunc'.
Solution:   Support using a lambda or partial. (Yegappan Lakshmanan,
            closes vim/vim#8775)
777175b0df

Omit duplicate docs. It's removed in patch 8.2.3623.
Nvim doesn't seem to need callback_set() as it was omitted when patch 8.1.1437
was first ported.
