GlueGen Struct [2]: Add CodeUnit: Representing a generated C or Java file, covering multiple FunctionEmitter allowing to unify output, decoration and dynamic helper code injection per unit

- Handles file open and have public ctor emitAutogeneratedWarning(..), being self-contained

- Includes `JVMUtil_NewDirectByteBufferCopy(..)` implementation in CCodeUnit,
  may be injected if required in customCode via emitHeader(..)
