Added implementations for *io/fs.subFS, os.DirFS, and testing/fstest.MapFS.
Amended testing/fstest.TestFS to check behavior.
Addressed TODOs in archive/tar and os.CopyFS around symbolic links.
I am deliberately not changing archive/zip in this CL,
since it currently does not resolve symlinks
as part of its filesystem implementation.
I am unsure of the compatibility restrictions on doing so,
so figured it would be better to address independently.
testing/fstest.MapFS now includes resolution of symlinks,
with MapFile.Data storing the symlink data.
The behavior change there seemed less intrusive,
especially given its intended usage in tests,
and it is especially helpful in testing the io/fs function implementations.
Fixes#49580

TestFS now returns a structured error built with errors.Join to allow to
inspect errors using errors.Is and errors.As.
All errors are now wrapped using fmt.Errorf and %w.
Fixes#63675.
