Potential FPE suppression/hiding in `GsfUtils.hpp`

https://github.com/acts-project/acts/blob/c0e65bc9ee2d99eca81a7098bd43653e071e3200/Core/include/Acts/TrackFitting/detail/GsfUtils.hpp#L197-L200

This looks like silent FPE treatment which might either come from the `chi2` being too large pushing `detR` to `inf` or caused by `detR` being negative in case the covariance is already broken. Both should in principle not happen but we protect against it and silence any occurrence right now.

In https://github.com/acts-project/acts/pull/3449 I observed an FPE at https://github.com/acts-project/acts/blob/c0e65bc9ee2d99eca81a7098bd43653e071e3200/Core/include/Acts/TrackFitting/detail/GsfUtils.hpp#L195 which indicates that `detR` is negative and this should only happen if at least one of the covariances is broken.
