QEE: Migrate the single muon HLT2 lines to ThOr

FYI @wbarter @hyin @lugrazet

Shifters please ignore

Now that ThOr has a SUMCONE functor, the HLT2 single, high-pt muon lines can be migrated to ThOr. At the moment, this functor does not remove the signal track from the cone, so the signal is manually removed by removing the track's pT from the sum. When the signal removal is added to SUMCONE, this can be removed. I will open an issue to make sure this is tracked.

Very small change in efficiency firing on 1k Z \to \mu\mu events on the CanRecoChildren denominator from LoKi (top) to ThOr (bottom):

Line:	 Hlt2SingleHighPtMuonIsoDecision               	 Efficiency:	 0.970 +/- 0.015

Line:	 Hlt2SingleHighPtMuonIsoDecision               	 Efficiency:	 0.978 +/- 0.013

Rates now (measured on 50k HLT1-filtered min bias):

Line:	 Hlt2SingleHighPtMuonIsoDecision     	 Incl: 0.13999 +/- 0.0529 kHz,	Excl: 0.12000 +/- 0.0489 kHz
Line:	 Hlt2SingleHighPtMuonDecision        	 Incl: 0.04 +/- 0.0282 kHz,	Excl: 0.02 +/- 0.0199 kHz
Line:	 Hlt2SingleHighPtMuonNoMuIDDecision  	 Incl: 0.24000 +/- 0.0692 kHz,	Excl: 0.24000 +/- 0.0692 kHz
Line:	 Hlt2SingleHighPtMuonPrescaleDecision	 Incl: 0.04 +/- 0.0282 kHz,	Excl: 0.04 +/- 0.0282 kHz

Previous LoKi-based implementation:

Line:	 Hlt2SingleHighPtMuonIsoDecision         Incl: 0.12 +/- 0.04 kHz, Excl: 0.08 +/- 0.03 kHz
Line:	 Hlt2SingleHighPtMuonDecision            Incl: 0.04 +/- 0.02 kHz, Excl: 0.0  +/- 0.0  kHz
Line:	 Hlt2SingleHighPtMuonNoMuIDDecision      Incl: 0.36 +/- 0.08 kHz, Excl: 0.22 +/- 0.06 kHz
Line:	 Hlt2SingleHighPtMuonPrescaleDecision    Incl: 0.02 +/- 0.01 kHz, Excl: 0.0  +/- 0.0  kHz

So compatible within uncertainties.
