maflckoandMarcoFalke fcf3fe37c6 gsl::not_null: C.89: Make a hash noexcept (#1236) ...

Without this change, the guideline
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c89-make-a-hash-noexcept
would be violated.

The test fails before the changes here:

```
tests/pointers_tests.cpp:102:23: error: static assertion failed due to requirement 'noexcept(std::hash<gsl::not_null<std::shared_ptr<int>>>{}(std::declval()))': gsl::not_null hash operator must be noexcept
  102 |         static_assert(noexcept(std::hash<Key>{}(std::declval<Key>())),
      |                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tests/pointers_tests.cpp:108:23: error: static assertion failed due to requirement 'noexcept(std::hash<gsl::strict_not_null<std::shared_ptr<int>>>{}(std::declval()))': gsl::strict_not_null hash operator must be noexcept
  108 |         static_assert(noexcept(std::hash<Key>{}(std::declval<Key>())),
      |                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
