Allow to preconfigure multiple test frameworks, rather than just one. #3632
Description
Is your feature request related to a problem? Please describe.
I'd like to be able to run a few chosen test frameworks within a project, optimally skipping automatic test framework detection for better performance.
Describe the solution you'd like
Currently, the --test-framework CLI option and //> using testFramework directive allow to configure a single test framework to be run.
I'd like an option to configure multiple this way.
Describe alternatives you've considered
One can always run multiple scala-cli test commands, each time with a different --test-framework param.
