This patch removes all of the frozen headers which don't provide anything. Basically any header that's C++11-or-later is removed from the frozen headers.

This is part of https://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc.

@llvmbot llvmbot added the libc++ libc++ C++ Standard Library. Not GNU libstdc++. Not libc++abi. label Apr 2, 2025

LGTM w/ passing CI.

One thing to note is that this might make it more difficult to backport some fixes to the frozen headers, but if that's the order you want to do this in, I'm fine with that.

In your commit message, please explain what you're doing, and the fact that this relates to the C++03 freeze. Most people are not super familiar with the whole thing, so this will be really helpful context to most.
