This change is almost fully mechanical. The only interesting change is in `generate_feature_test_macro_components.py` to generate `_LIBCPP_STD_VER >=` instead. To avoid churn in the git-blame this commit should be added to the `.git-blame-ignore-revs` once committed.

By default, Clang does not include headers that are skipped due to
the include guard optimization in the --trace-includes output, which
breaks the use case that we were trying to use it for.
However, Clang does support the -fshow-skipped-includes flag, which
does exactly what we need and will result in an accurate include
graph.
As a fly-by fix, make sure that our includes don't differ between
-fexceptions and -fno-exceptions.

This version is build without support for the experimental library but
the code still wants to link this function. Inlining the function solves
the issue.

This commit reverts 5aaefa51 (and also partly 7f285f48e77 and b6d75682f9,
which were related to the original commit). As landed, 5aaefa51 had
unintended consequences on some downstream bots and didn't have proper
coverage upstream due to a few subtle things. Implementing this is
something we should do in libc++, however we'll first need to address
a few issues listed in https://reviews.llvm.org/D106124#3349710.

libc++ has started splicing standard library headers into much more
fine-grained content for maintainability. It's very likely that outdated
and naive tooling (some of which is outside of LLVM's scope) will
suggest users include things such as <__ranges/access.h> instead of
<ranges>, and Hyrum's law suggests that users will eventually begin to
rely on this without the help of tooling. As such, this commit
intends to protect users from themselves, by making it a hard error for
anyone outside of the standard library to include libc++ detail headers.

This replaces _LIBCPP_INLINE_VISIBILITY with _LIBCPP_HIDE_FROM_ABI. It's
not intended to do for other parts of libc++. This change makes it easy
to search and replace all occurrences of the patches in review.
