Add new flags to disable NSW only for L2 (ATR-27714)

Dear all,

This MR addresses the issue discussed in ATR-27714, which allows us to disable the NSW only in L2SA reconstruction but enable it in EFSA.

MuonSpectrometer/MuonConfig/python/MuonConfigFlags.py was updated to add a new flag for trigger Muon.disableNSWForL2SA.

Trigger/TrigAlgorithms/TrigL2MuonSA/python/TrigL2MuonSAConfig.py was updated to propagate the Muon.disableNSWForL2SA to enable/disable the use of the NSW in L2SA, including Muon.disableNSWForL2SA.

Trigger/TriggerCommon/TriggerMenuMT/python/HLT/Muon/MuonMenuSequences.py was updated to propagate the Muon.disableNSWForL2SA and Muon.runCommissioningChain to TrigL2MuonSAConfig.py.
