Remove need for `configure` block in extension

[05nelsonm]

Need to investigate how to use Gradle's Lazy Configuration in order to remove the need to have the configure block, in favor of simply configuring things once the task is completed.

Currently

kmpConfiguration {
    configure {
        jvm {
            // ...
        }

        // ...
    }
}

My Hope

kmpConfiguration {
    jvm {
        // ...
    }

    // ...
}
