Single relocation declaration

- Add gradle/runtime-relocations.gradle as the one runtime-download relocation map
- Read the slimJar relocations and shrinkRelocations from that map
- Pass the derived relocation prefixes into BukkitArtifactVerifier
- Drop the duplicate jar size check the packaging audit already enforces
