Update Gradle plugins publishing setup

Simplifies and make it aligned with official documentation, which
removes some old workarounds. Additionally, it enables publication of
Gradle metadata file, which is required for plugin variants feature
support.

Instead of using 'gradleApi()' as Gradle API dependency, which provides
build current Gradle version api, now setup is using
"dev.gradleplugins:gradle-api" artifacts with specific Gradle version.
This allows to have more fine-grained Gradle support for removed apis.
