py/modio: Remove FileIO and TextIOWrapper from io module.

On ports with more than one filesystem, the type will be wrong, for example
if using LFS but FAT enabled, then the type will be FAT.  So it's not
possible to use these classes to identify a file object type.

Furthermore, constructing an io.FileIO currently crashes on FAT, and
make_new isn't supported on LFS.

And the io.TextIOWrapper class does not match CPython at all.
