Don't modify features based on binary name

[tgodzik]

Is your feature request related to a problem? Please describe.
Currently, if you use ScalaCLI as scala you will need to use --power to use advanced feature. This is not the case when changing the name of the binary. This basically means we would need two kinds of documentation and makes it necessary to have two different releases.

We discussed it with both @julienrf and @romanowski that in the end we would only want to have a single scala runner with the ability to use --power options or using #1823 to transform scala into a full scala runner.

This also allows us to have a single documentation page with the advanced features clearly marked via #1700

Describe the solution you'd like
Let's make the behaviour with scala as the default.

Describe alternatives you've considered
Keep it as it is or do the update later on.
