Cleanup build logic

[whyoleg]

Overall, the idea is that latest Gradle/KGP versions and suggesting allowed to cleanup some code.

Just build-related changes:

• align build-logic naming with what Gradle suggests
  • move build-logic to root of the project
• introduce build-logic-settings
• remove build-parameters
• move kotlin version to Version Catalog
• extract Gradle related versions to Version Catalog
• drop target-specific convention plugins, as KGP now generates accessors
• use targets helpers in projects instead of convention plugins
• drop template convention plugins, leave only library - inline other usages

Code/functionality related changes:

• run tests on JDK 21
• minor cleanup in the publication script
• create test aggregate tasks (to run by CI)
• reduce usages of OptIns
• use jvm-default=all (easier compatibility in future)
• drop test server completely for now from rsocket-transport-tests
