Dario Mirovic f01efd822e utils: add result_with_exception_ptr ...

Add `result_with_exception_ptr` result type.
Successful result has user specified type.
Failed result has std::exception_ptr.

This approach is simpler than `result_with_exception`. It does not require
user to pass exception types as variadic template through all the callstack.
Specific exception type can still be accessed without costly std::rethrow_exception(eptr)
by using `try_catch`, if configured so via `USE_OPTIMIZED_EXCEPTION_HANDLING`.
This means no information loss, but less verbosity when writing result types.
