Partially revert hypot arguments zero checks

Unfortunately, libc++'s 3-argument std::hypot implementation is
numerically unstable until LLVM 19.x. Therefore, checking the arguments
for zeros is insufficient since an underflow can still occur resulting
in a zero norm which requires another check. As such, division by zero
cannot be reliably avoided.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
