PR libstdc++/83306 make filesystem_error no-throw copyable
The class API provides no way to modify the members, so we can share
them between copies of the same object. Copying becomes a simple
reference count update, which doesn't throw.
Also adjust the what() string to allow distinguishing between an empty
path passed to the constructor, and no path.
