Removed boost dependency in RecoLocalMuon/DTSegment

[camolezi]

PR description:

Replaced boost library use for C++ STL alternatives. All the code should have similar behavior.

Notes:

• std::unordered_set demands a hasher class(TriedPattern::HashFunction) for custom classes as keys.

• hash_combine is the same implementation as in boost::hash_combine.

PR validation:

Passed on basic runTheMatrix test.

• Technical (although not trivial: reviewing this PR was a good gym to learn the differences betweed std::unordered_set and boost::unordered_set)
• Jenkinst tests pass

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo (and backports should be raised in the release meeting by the corresponding L2)
