throw() -> noexcept, part 1/3: Manual scaffolding

The legacy `throw()` dynamic exception specification is gone for good from C++20
(even if compilers typically still accept it, but e.g. Clang has
-Wdeprecated-dynamic-exception-spec to at least warn about it).

Introduce SAL_NOEXCEPT for use in URE interface include files.  (For both the
existing SAL_THROW_EXTERN_C and the new SAL_NOEXCEPT, base usage of `noexept`
not on LIBO_INTERNAL_ONLY, but on the actual compiler C++ version, so that e.g.
building CppunitTest_cppu_any-external, which uses
gb_CppunitTest_set_external_code but not gb_CXX03FLAGS, will not potentially
complain about those macros expanding to the legacy `throw()`, like when
building with Clang -Wdeprecated-dynamic-exception-spec manually enabled.)
