Currently the launcher API uses hard-coded modular VM options. We could use a properties file to set VM options. An example file might look something like:

vm.options=-Xms512m
vm.options.modular=--add.modles=java.se --add-opens=java.base/java.security=ALL-UNNAMED
vm.options.17=--add-opens=java.naming/javax.naming=ALL-UNNAMED
vm.options.windows=-Xmx=1024m

Bonus points if we can figure out a way to do this for scripts too. One idea for this would be to generate files, maybe in the common.conf, with something like JBang during the build.
