[libc++][NFC] Make __desugars_to a variable template and rename the header to desugars_to.h (#87337)
This improves compile times and memory usage slightly and removes some boilerplate. |

[libc++] Unify __is_trivial_equality_predicate and __is_trivial_plus_operation into __desugars_to (#68642)
When working on an OpenMP offloading backend for standard parallel algorithms (https://github.com/llvm/llvm-project/pull/66968) we noticed the need of a generalization of `__is_trivial_plus_operation`. This patch merges `__is_trivial_equality_predicate` and `__is_trivial_plus_operation` into `__desugars_to`, and in the future we might extend the latter to support other binary operations as well.

[libc++] Refactor __less
This simplifies the usage of `__less` by making the class not depend on the types compared, but instead the `operator()`. We can't remove the template completely because we explicitly instantiate `std::__sort` with `__less<T>`.

[libcxx][modules] protects users from relying on detail headers
libc++ has started splicing standard library headers into much more fine-grained content for maintainability. It's very likely that outdated and naive tooling (some of which is outside of LLVM's scope) will suggest users include things such as <__ranges/access.h> instead of <ranges>, and Hyrum's law suggests that users will eventually begin to rely on this without the help of tooling. As such, this commit intends to protect users from themselves, by making it a hard error for anyone outside of the standard library to include libc++ detail headers.

[libcxx] Move all algorithms into their own headers
This is a fairly mechanical change, it just moves each algorithm into its own header. This is intended to be a NFC. This commit re-applies |

[libcxx][gardening] Move all algorithms into their own headers.
This is a fairly mechanical change, it just moves each algorithm into its own header. This is a NFC. Note: during this change, I burned down all the includes, so this follows "include only and exactly what you use." Differential Revision: https://reviews.llvm.org/D103583 |
