[NFC][Py Reformat] Reformat python files in the rest of the dirs
This is an ongoing series of commits that are reformatting our
Python code. This catches the last of the python files to
reformat. Since they where so few I bunched them together.

Reformatting is done with `black`.

If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.

If you run into any problems, post to discourse about it and
we will try to help.

5b0502dff5 [pstl] A fix for move placement-new (and destroy) allocated objects from raw memory.
https://reviews.llvm.org/D74123

The fix affects follow algorithms:
remove_if, unique, rotate, inplace_merge, partial_sort_copy, set_union, set_intersection, set_difference, set_symmetric_difference.

For "is_trivial" types there are no problems with "creating objects/clean-up"
For non-trivial types the algo results are also correct, but possible incorrect copying/moving "operator=" calls "by raw memory" within one of mentioned algo or incorrect destructor calls in the end of algo.

0a06eb911b [libc++] Take 2: Integrate the PSTL into libc++
Summary:
This commit allows specifying LIBCXX_ENABLE_PARALLEL_ALGORITHMS when
configuring libc++ in CMake. When that option is enabled, libc++ will
assume that the PSTL can be found somewhere on the CMake module path,
and it will provide the C++17 parallel algorithms based on the PSTL
(that is assumed to be available).

The commit also adds support for running the PSTL tests as part of
the libc++ test suite.

The first attempt to commit this failed because it exposed a bug in the
tests for modules. Now that this has been fixed, it should be safe to
commit this.

5c4c44310a [pstl] Remove various warnings in the pstl headers and tests
- unused parameter warnings
- don't use single-letter template parameter names, like we do in libc++
- sign-comparison warnings
- unused variables in the tests
- unused local typedefs in the tests
- the use of #include_next
- field reordering in the tests
- unused lambda captures

Note that the rationale for why the static_casts to unsigned are OK is
that last - first must always be non-negative, since [first, last) is
a valid range.

4d88b17b3f [pstl] Remove the stdlib headers from the PSTL and move them to the tests
Summary:
PSTL should not provide those headers since they belong to the standard
library. Instead, we define a dummy standard library in the tests that
provides those headers.

1dd1b5d5f2 [pstl] Introduce forward declarations
Necessary when pstl is included from with <algorithm> and <numeric> to
prevent a partially declared standard library when pstl itself uses
algorithms from <algorithm> and <numeric>.

Also, this patch makes sure that configuration comes via standard headers.
Directly including pstl_config.h in implementation files is incompatible
with inclusion of pstl into a standard library implementation which
provides it's own library wide configuration and may configure the
library differently to the pstl_config.h used by the standalone
implementation.
