Deanna Garcia f5ffaf9063 Remove unused pom.xml files. We mostly use generated pom files in our release currently, so we can delete all the files that aren't used and the tools to update them. Note, java/bom/pom.xml java/pom.xml and java/protoc/pom.xml are all still used at release and java/kotlin/pom.xml is used for documentation so all of those need to stay for now.
