feat(dokka): implement integrated Dokka support

[teogor]

Description

This PR implements integrated support for Dokka, streamlining the generation of API documentation for Kotlin projects through the winds extension.

Changes

• DokkaUtils.kt: Created a new utility to handle Dokka plugin application.
• WindsPlugin.kt: Integrated configureDokka into the plugin lifecycle.

Usage

Enable Dokka in your build.gradle.kts:

winds {
    features {
        dokka = true
    }
}

Verification

• Verified that org.jetbrains.dokka is applied to the project when the feature is enabled.
• Confirmed task availability (./gradlew dokkaHtml) after application.
