L1Decoder: Seed HLT from Run-3 L1Muon simulation output (xAOD::MuonRoI)

Changes:

1. Split the roiUnpackers tool array in L1Decoder into legacy RoIB unpackers and Run-3 xAOD unpackers. Update all clients and the configuration to reflect this change.
2. Handle the "emulation" mode of running by adding explicit flag method in CTP unpacker and explicitly handling the different modes of running in L1Decoder.
3. Change the IRoIsUnpackingTool interface by introducing an overloaded unpack method using xAOD EDM instead of RoIBResult. In principle this could be split into separate interfaces, but the configuration is common so this avoids code duplication. If needed, the split can be done later once we migrate more objects to xAOD.
4. Implement the xAOD unpack method for MURoIsUnpackingTool.
5. Add a new test in TriggerTest which runs muon triggers seeded from Run-3 L1Muon simulation. The test actually fails right now because the downstream HLT code ("L2" muon algorithms) depends on the old Run-2 EDM. The test is needed to aid the adaptation of the downstream code to the new L1 EDM.

Tested with:

with some extra print-outs (now removed) which proved the code works as expected:
