It should be possible to use `File` objects returned by `FileField` in a
`io.TextIOWrapper`.

e.g.

{{{#!python
import csv
from io import TextIOWrapper

with TextIOWrapper(model_instance.csv_file, 'utf-8') as wrapper:
reader = csv.reader(wrapper)
...
}}}

This requires adding the missing `readable()`, `writable()` methods and
making the `seekable()` method of `FileProxyMixin()` available even on
Python 2 (#24963 added it for Python 3 only).
