makefile: add open_ variants of gui_

the usecase is to run openroad in console mode.

This can be used by humans, but also for scripting.

For instance: inject a command or two and then parse the
output. Convenient for quick and dirty Python scripts to plot something,
for instance.

To start OpenROAD in console mode with the final result:

make open_final
