vim-patch:8.2.4723: the ModeChanged autocmd event is inefficient

Browse Source 
Problem:    The ModeChanged autocmd event is inefficient.
Solution:   Avoid allocating memory. (closes vim/vim#10134)  Rename
            trigger_modechanged() to may_trigger_modechanged().

Make v:event readonly for ModeChanged.
