Marek Kurdej e4ed349c76 [libc++] [P1164] [C++20] Make fs::create_directory() error if there is already a non-directory. 
Also mark LWG2935 and LWG3079 as complete.

Applied retroactively to previous standards too, as it's a DR.

Marek Kurdej 877170f3eb [libc++] [LWG3221] Add tests for wrapping operator+(year_month, months). 
The behaviour didn't change since commit 5b08c1742a (Recommit <chrono> changes with a couple xtra tests marked to fail on apple's clang.)

Marek Kurdej ba3adfad6e [libc++] Mark LWG3200 as Nothing To Do. NFC. 
This is only a wording change, because it is currently impossible to constrain the overload set on whether the type is complete or not.

Marek Kurdej bf8683adfa [libc++] [docs] Mark LWG3055 as complete. Use string_view instead of string in path::operator+=(ECharT). 
The issue didn't change the behaviour which is tested in libcxx/test/std/input.output/filesystems/class.path/path.member/path.concat.pass.cpp.

The change to use string_view instead of string is not strictly necessary.

<filesystem> was added in commit 998a5c8831 (Implement <filesystem>).

Marek Kurdej a5f98b5419 [libc++] [docs] Migrate C++ status pages to RestructuredText (RST). 
Currently, papers and issues are in separate .csv files (that is easier to update), but I can put them inline.Transforming current html tables into rst are done by the script (attached to the patch FYI but I'll remove it before committing).
I'll of course update RST files before committing to match any modifications that may happen in master branch.

This patch moves the status pages in www/ to RST format in docs/.

It also does some other minor changes: fix copyright year and broken comment end, adds substitutions for coherence (and add colors, but that can be removed easily).
It adds as well redirects from old to new status pages.
