Break a dependency between detekt-gradle-plugin and detekt-utils

[cortinico]

I'm removing a dependency between detekt-gradle-plugin and detekt-utils. This is making harder to move to a composite build + it's an unnecessary dependency as we just use a function from detekt-utils.

This also causes build failures for users if detekt-gradle-plugin is published and detekt-utils is not yet. See #4696 (comment)
