Maxwell A McKinnon cf57cabef8 bpo-32689: Updates shutil.move to allow for Path objects to be used as source arg (GH-15326)
Important work originally done by @emilyemorehouse two years ago and nearly ready to go in.

This bug has affected many people and in some cases has been a dealbreaker to the adoption of the otherwise wonderful pathlib and PEP519. https://stackoverflow.com/questions/33625931/copy-file-with-pathlib-in-python.

This adds the outstanding test request from that PR @vstinner (https://github.com/python/cpython/pull/5393).

Test fails without the change, passes with it, along with every other test in test_shutil.

Some variants were experimented with to make the one line change and the most performant one was picked.

# Performance Considerations
Is it considered poor form to get rid of _basename altogether and make use of pathlib in the move function? I'm not sure if the idea is for all these modules to strictly avoid circular dependencies. They are already using os.path which is just as much a citizen in 3.8 as pathlib right?

e.g.

`real_dst = os.path.join(dst, _basename(src))`
becomes
`real_dst = Path(dst) / Path(src).name`

I've looked around and familiarized myself, and I now think importing pathlib here is fine. My only remaining concern is that of performance.

Here's the performance difference for this step. 

```
In [46]: %timeit real_dst = os.path.join("a/b/c", _basename('b/'))
2.71 µs ± 62.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

In [47]: %timeit real_dst = Path("a/b/c") / Path('b/').name
12.4 µs ± 65.3 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)
```

Is 10us significant or insignificant compared to the least expensive operation this function will do? I don't know. Let's find out.

```
In [55]: %timeit os.rename('/tmp/a/a.txt', '/tmp/a/b.txt'); os.rename('/tmp/a/b.txt', '/tmp/a/a.txt')
124 µs ± 2.18 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
```
62us to rename. 10us seems significant enough that we wouldn't want to favor the Path sugar suggestion. 16% speed decrease from adding the 10us.

What do people think? I was hoping to get to use pathlib.Path here, but I suspect for this low level move, it should be as fast as possible, and 16% is not worth one line of sugary code to me.

This avoids the buildbot failure on Windows:
```
FileNotFoundError: [WinError 206] The filename or extension is too long: 'd:\\temp\\tmp5r3z438t\\long\\1\\2\\3\\4\\5\\6\\7\\8\\9\\10\\11\\12\\13\\14\\15\\16\\17\\18\\19\\20\\21\\22\\23\\24\\25\\26\\27\\28\\29\\30\\31\\32\\33\\34\\35\\36\\37\\38\\39\\40\\41\\42\\43\\44\\45\\46\\47\\48\\49\\50\\51\\52\\53\\54\\55\\56\\57\\58\\59\\60\\61\\62\\63\\64\\65\\66\\67\\68\\69\\70\\71\\72\\73\\74\\75\\76\\77\\78'
```
Creates a path that's long but avoids OS restrictions.
