[libc++] Re-add transitive includes that had been removed since LLVM 14
This commit re-adds transitive includes that had been removed by

[libc++] Re-add transitive includes that had been removed since LLVM 14
This commit re-adds transitive includes that had been removed by
4cd04d1687f1, c36870c8e79c, a83f4b9cda57, 1458458b558d, 2e2f3158c604,
and 489637e66dd3. This should cover almost all the includes that had
been removed since LLVM 14 and that would contribute to breaking user
code when releasing LLVM 15.
It is possible to disable the inclusion of these headers by defining
_LIBCPP_REMOVE_TRANSITIVE_INCLUDES. The intent is that vendors will
enable that macro and start fixing downstream issues immediately. We
can then remove the macro (and the transitive includes) by default in
a future release. That way, we will break users only once by removing
transitive includes in bulk instead of doing it bit by bit a every
release, which is more disruptive for users.
Note 1: The set of headers to re-add was found by re-generating the
transitive include test on a checkout of release/14.x, which
provided the list of all transitive includes we used to provide.
Note 2: Several includes of <vector>, <optional>, <array> and <unordered_map>
have been added in this commit. These transitive inclusions were
added when we implemented boyer_moore_searcher in <functional>.
Note 3: This is a best effort patch to try and resolve downstream breakage
caused since branching LLVM 14. I wasn't able to perfectly mirror
transitive includes in LLVM 14 for a few headers, so I added a
release note explaining it. To summarize, adding boyer_moore_searcher
created a bunch of circular dependencies, so we have to break
backwards compatibility in a few cases.

[libc++] Add a test to pin down the set of transitive public includes
A situation that happens fairly often in libc++ is that we remove some
transitive includes in a header (either purposefully or not) and that
ends up breaking users. Of course, we want to be able to remove our
transitive includes, however it's also good to have a grip on that
to know which commit changed what and when. Furthermore, it's good
to accumulate include removals for a couple of releases to avoid
breaking users at every release for this reason.
This commit adds a test that should break whenever we remove an
include. Hence, it should allow us to track which headers include
which other headers transitively, giving us a traceable way to
remove headers.
