MDEV-25152 Insert linebreaks in mysqldump --extended-insert

Browse Source 
Currently, mysqldump --extended-insert outputs all rows on a single line,
which makes it difficult to use with various Unix command-line utilities
such as grep and diff.

We change mysqldump to emit a linebreak between each row, that would make
it easier to work with, without significantly affecting dump or restore
performance, or affecting compatibility.

Closes: #1865
