Create and publish Besu BOM (Bill of Materials)

[fab-10]

PR description

Introducing Besu BOM (bill of materials) to improve the way we manage shared dependencies between Besu and plugins.
It is based on Gradle Java Platform plugin and it is also used internally, replacing the Spring Dependency Manager, it is then published as BOM artifacts so it can be used as reference in plugins for all the dependencies that are in common with Besu, this way it is easier to spot dependencies incompatibilities when developing plugins.
