HBX-2733: Create Interface for Cfg2HbmWrapper

  - Create new test class 'org.hibernate.tool.orm.jbt.api.Cfg2HbmToolWrapperTest'
  - Create new interface class 'org.hibernate.tool.orm.jbt.api.Cfg2HbmToolWrapper'
  - Create new factory class 'org.hibernate.tool.orm.jbt.internal.factory.Cfg2HbmToolWrapperFactory'
