BugFix for L3MuonCandidateProducerFromMuons

[folguera]

Matching efficiency was degrading for very high-pt muons, this brings back the possibility of using the innerTrack when available and using the outerTrack otherwise.

This is a backport of #22774

[cmsbuild]

A new Pull Request was created by @folguera (Santiago Folgueras) for CMSSW_10_1_X.

It involves the following packages:

RecoMuon/L3MuonProducer

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_10_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
