Refactor OutputGroups to handle effective values, fees, and filtering

Summary:
Instead of having callers set the fees, effective values, and filtering
of outputs, do these within OutputGroups themselves as member functions.

m_fee and m_long_term_fee is added to OutputGroup to track the fees of
the OutputGroup.

This is a backport of core#17458 [2/2]
