   ## What is the purpose of the change
   
   This PR calculates managed memory fraction for each operator based on the slot sharing group resources and set the result into StreamConfig.
    - For operators with specified ResourceSpecs, calculate fractions according to operators ResourceSpecs
    - For operators with unknown ResourceSpecs, calculate fractions according to number of operators
   
   This change is based on #10079 and #10179.
