Add trailing comma for single-element import-from groups (#6583)

Browse source 
## Summary

Unlike other statements, Black always adds a trailing comma if an
import-from statement breaks with a single import member. I believe this
is for compatibility with isort -- see
09f5ee3a19,
https://github.com/psf/black/issues/127, or
66648c528a/src/black/linegen.py (L1452)
for the current version.

## Test Plan

`cargo test`, notice that a big chunk of the compatibility suite is
removed.
