382cf33824 Add test for GCC 12+ -Wmaybe-uninitialized false positive 
Add variant_gcc_false_positive.cpp to reproduce GCC 12+ spurious
-Wmaybe-uninitialized warnings when copying/moving variant containing
non-trivially-copyable types like std::exception_ptr and std::string.

Tests use boost::system::result which internally uses variant2, and
include coroutine-based tests when C++20 coroutine support is available.

The test uses -O3 optimization to trigger the aggressive inlining that
exposes the false positive where GCC's dataflow analysis cannot prove
the discriminator ensures only initialized alternatives are accessed.
