Reduce boost dependency in L1Trigger/TrackFindingTMTT

[camolezi]

PR description:

Replaced boost::numeric::ublas::matrix for a wrapped std::vector.
Since the boost::matrix here is used basically as an fixed indexed storage, a std::vector replacement should not impact performance significantly.

PR validation:

Passed on basic runTheMatrix test.

I've made a few benchmarks to measure performance differences. And in theory, it should not be significant in this use case.
