Add a config option to turn on power features

[tgodzik]

Is your feature request related to a problem? Please describe.
When using scala-cli as the scala runner whenever you want to use an advanced option you need to add --power, which might not be the best UX experience when using a lot of advanced options

Describe the solution you'd like
Have a way to turn it on as a default:
scala config --power

or

scala config --power true

or

scala config power true

Describe alternatives you've considered
Always add --power

Additional context
When merging scala-cli and scala into one functionality it will be required to get a smooth transition for the users of previous scala-cli versions
