UseJava: Quote -classpath argument correctly on more platforms

Add the `VERBATIM` option to our `add_custom_command` calls so that all
arguments are correctly escaped for the shell.  Otherwise when using a
POSIX shell on Windows, the `-classpath` separator is `;` and without
quoting ends the command.

Fixes: #20567
