EgammaFast step code harmonization
This MR is also related to ATR-20143.
The main purpose here is to harmonize all Egamma fast step code in order to follow the Run 3 nomenclature. The main modification is:
- In all codes that have MT, AlgMT or HypoTools a TrigEgammaFast prefix was added this also includes the .py files;
- Remove unused functions in TrigMultiVarHypo .py file.
All legacy codes were maintained.
