vim-patch:9.1.1193: Unnecessary use of STRCAT() in au_event_disable() (#32829)

Browse Source 
Problem:  Unnecessary use of STRCAT() in au_event_disable().  STRCAT()
          seeks to the end of new_ei, but here the end is already known.
Solution: Use STRCPY() and add p_ei_len to new_ei.  Also fix a typo in a
          comment.  Add a test that 'eventignore' works in :argdo
          (zeertzjq).

closes: vim/vim#16844

Cherry-pick p_ei_len from patch 9.1.0256.
