build: Update modules

Produced by running:

    python3 build/modules/modularize/modularize.py --no-cache

It created a few changes. Maybe nobody has run this since switching
to C++23?

I used https://chromium-review.googlesource.com/c/chromium/src/+/7786175
to be able to run the modularize script at all.

I manually updated libc++/BUILD.gn and libc++/modules.gni to match
(for iOS and for mac builds with system Xcode). These builds still
use hermetic libc++ and hermetic clang, and the changes look like
they depend on libc++ and clang.

No intended behavior change.
