This implements a limited exception mechanism for find_package() via the UNWIND_INCLUDE keyword. When package discovery via find_package(UNWIND_INCLUDE) fails the StateSnapshot is updated to an UNWINDING state. In this state further calls to find_package() and include() are forbidden. While in the UNWINDING state, the include() command immediately calls SetReturnInvoked() whenever it is reached. The UNWINDING state is reset when a parent call to find_package() is reached. Fixes: #26897
