  Log Message:
  -----------
  [libc++][RFC] Only include what is required by-version in the umbrella headers (#83740)

This is a relatively low cost way of reducing the include sizes in older
language modes compared to the effect. For example, in C++14 mode the
include time of `<algorithm>` is reduced from 198ms to 127ms.
