[build] Rewrite shadow relocation; fix dependency graph issues with Android, and improve build performance:

- Generate relocated JARs with classifier `relocated`, instead of replacing the output of `:jar` task.

- Create `JvmRelocated` publications to publish relocated artifacts.

- Patch Kotlin Metadata and Maven Pom for the added publication.

- Updated deps test to be more strict
