Make KalmanVertexOnJetAxisSmoother more robust against FPE (ATLASRECTS-7784)

Similar to !66377 (merged), update invertibility check of covariance matrix of vertex with isInvertible method from LU decomposition.

Checked to leave Run 3 reco q445 test outputs unchanged.

Aimed at 23.0 as it affects HeavyIon Tier-0 processing.
