Ladybird: Add `--force-new-process` option

This option skips attempting any chrome IPC which even with the
`--new-window` does not open a new browser process. This is annoying
when trying to compare browser options as opening a new window with
the currently running chrome ignores any options passed to the new
ladybird invocation.
