Nikolas Klauser c166a9c713 [libc++] Add #if 0 block to all the top-level headers (#119234)
Including The frozen C++03 headers results in a lot of formatting
changes in the main headers, so this splits these changes into a
separate commit instead.

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

This usually means that your header search paths are not configured properly. \
The header search paths should contain the C++ Standard Library headers before \
any C Standard Library, and you are probably using compiler flags that make that \
not be the case.

// Based on the post commit feedback the macro are no longer deprecated.
