Add .clang-format to libc++ Adding a Clang Format file to libc++ and which style it should use has been discussed a couple of times. This patch finally adds a .clang-format file which specifies LLVM styles. Personally I dislike how the LLVM style handles much of the meta-programming in libc++. However the general consensus was that libc++ should prefer the LLVM style and make adjustments where needed. Note that using clang-format on changes is not required, especially for changes within the headers. However formatting tests should be encouraged. llvm-svn: 287020

[libcxx] Fix max_size() across all containers Summary: The `max_size()` method of containers should respect both the allocator's reported `max_size` and the range of the `difference_type`. This patch makes all containers choose the smallest of those two values.

[libc++] Find a clang-format everybody is happy with We decided that we want to use clang-format for libc++ but we haven't decided yet how the code should be formatted. We should probably discuss things on discord. This PR is mostly to show how the clang-format would look like and to commit to one once we decided on it. I'll remove the `<string>` diff when I commit this PR.

[libc++] Update clang-format to C++20. We now use clang-format-13 which has the option SpacesInAngles. This allows us to switch the default language version to C++20, which should avoid breaking code when formatting due to the adding of whitespace. For example `u8"foo"` no longer is formatted as `u8 "foo"`. Reviewed By: #libc, ldionne Differential Revision: https://reviews.llvm.org/D112728
