Description: This shrinks the size of .pyc files by about 25%. It also removes an intermediate copy of the bytecode created during marshalling. Next steps will be removing the intermediate bytes object created during unmarshalling and performing the work of _PyCode_Quicken as part of this same move. Issue: gh-99554
