Add muon idperf chain for muon LRT primary to LS2_v1
Adding HLT_mu24_LRT_idperf_L1MU20 to LS2_v1 for performance support of the mu24 LRT chain.
I saw count changes for three unrelated photon chains. The same thing happened with another recent merge request and went away when the CI re-ran (!44425 (merged)])
The other tests I ran passed.
