Newer versions of gcc give warning for "error: template-id not allowed for constructor in C++20"

Reported by @agners on slack. Opening issue for @yyzhong-g to look into

gcc version 14.1.1 give warning and fails to compile on tip of tree after with the following error:

In file included from ../src/app/InteractionModelDelegatePointers.h:21,
                 from ../src/app/InteractionModelDelegatePointers.cpp:18:
../src/lib/support/static_support_smart_ptr.h:57:38: error: template-id not allowed for constructor in C++20 [-Werror=template-id-cdtor]
   57 |     CheckedGlobalInstanceReference<T>() = default;
      |                                      ^
../src/lib/support/static_support_smart_ptr.h:57:38: note: remove the '< >'
../src/lib/support/static_support_smart_ptr.h:92:31: error: template-id not allowed for constructor in C++20 [-Werror=template-id-cdtor]
   92 |     SimpleInstanceReference<T>() = default;
      |

Reverting #33426, or adding -Wno-error=template-id-cdtor, makes the issue go away
