Replace delete-trailing-whitespace with ws-butler

Browse Source 
ws-butler only strips trailing spaces on lines that have been modified.

+ ws-butler is disabled if editorconfig enables
  trim_trailing_whitespace, which resorts to delete-trailing-whitespace
  instead.
+ Updates doom|(enable|disable)-delete-trailing-whitespace hooks to use
  ws-butler-mode.
