TrkiPatFitterUtils: Optimize some functions, even in dbg builds.

The function FitMatrices::solveEquations makes heavy use of Eigen and runs extremely slowly in dbg builds. Adjust to compile this function with optimization, even in dbg builds. For the MuonCombinedConfig unit test, this results in a 10% speedup in the dbg build.
