MDEV-16238 root/localhost authn prioritizes authentication_string over Password

Browse source 
Don't let SET PASSWORD to set the password, if auth_string is set.

Now SET PASSWORD always sets the plugin/auth_string fields and clears
the password field (on pre-plugin mysql.user table it works as before).
