[libcxx-commits] [libcxx] [libc++] Granularize <vector> (PR #99705)

What is the motivation for this patch?

There were two goals when I originally started the modularisation of libc++ headers:

1. eliminate circular dependencies
2. separate completely unrelated entities

This was done with the intention of ensuring that including Header A didn't include all of Header B just for Function F, and to improve lookup (`<type_traits>` was the home of many things that it wasn't the prescribed home of).

Splitting `<vector>` into seven new headers doesn't achieve the first goal, and I'm not convinced it is achieving the second either.
