Feat: Use Besu plugin Gradle plugin

[fab-10]

Note

Switches the build to Besu plugin Gradle plugins, removes custom dependency/distribution logic, streamlines module deps, and updates test/distribution tasks.

• Build/Gradle:
  • Adopt net.consensys.besu-plugin-library and net.consensys.besu-plugin-distribution in root and modules; add plugin repo in settings.gradle.
  • Remove bespoke Gradle scripts (gradle/allprojects.gradle, gradle/common-dependencies.gradle, gradle/dist.gradle) and related Besu dep management; simplify gradle/dependency-management.gradle.
  • Update Java toolchain config to java { ... consistentResolution { useCompileClasspathVersions() } } in gradle/java.gradle.
  • Replace distPlugin with distZip and wire artifacts alias accordingly; adjust copyTracerPlugin to unzip distZip.
  • Add besuRepo property in gradle.properties and clean unused Besu coordinates.
• Modules:
  • arithmetization: trim dependencies to org.hyperledger.besu:gnark and testing libs; apply plugin library.
  • plugins: use Besu distribution plugin; set jar manifest/distributionIdentifier; configure distributions.
  • reference-tests and testing: apply plugin library; remove numerous Besu/tuweni deps; keep essential test libs and project links.
• Testing/Reports:
  • Keep Jacoco/Sonar setup; update test tasks to depend on new plugin distribution and maintain coverage reports.
