Some of the calendar types have landed before, this adds the missing
set. Note this does not complete the implementation of the chrono
formatters.
This removes the `chrono` header for some transitive include in C++17
mode. This is needed to avoid inclusion cycles.
Partially implements:
- P1361 Integration of chrono with text formatting
- P2372 Fixing locale handling in chrono formatters

Switch to the new granular format_functions header. Since the chrono's
format dependency in C++20 hasn't been in a release it's save to remove
it.

Instead of mentioning tm directly in the definition of __convert_to_tm,
take it as a template argument. As a fly-by also fix incorrect Lit feature
(should have been no-localization instead of libcpp-has-no-localization).

In our implementation the year is always less than or equal to the
class' `max()`. It's unlikely this ever changes since changing the
year's range will be an ABI break. A static_assert is added as a
guard.

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 It's very likely that outdated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.

As per [time.duration.cons]/1, the constructor constraint should be on
const Rep2&. As it is now the code will fail to compile in certain
cases, for example (https://godbolt.org/z/c7fPrcTYM):
struct S{
operator int() const&& noexcept = delete;
operator int() const& noexcept;
};
const S &fun();
auto k = std::chrono::microseconds{fun()};

It was not in P0355R7, nor has it ever been so in a working draft.
Drive-by:
* tests should test something: fix loop bounds so initial value is not >= final value
* calender type streaming tests are useless - let's remove them
* don't declare printf, especially if you don't intend to use it

This change is the basis for a further refactoring where I'm going to
split up the various implementations we have in __threading_support to
make that code easier to understand.
Note that I had to make __convert_to_timespec a template to break
circular dependencies. Concretely, we never seem to use it with anything
other than ::timespec, but I am wary of hardcoding that assumption as
part of this change, since I suspect there's a reason for going through
these hoops in the first place.

I didn't split the calendar bits more than this because there was little
benefit to doing it, and I know our calendar support is incomplete.
Whoever picks up the missing calendar bits can organize these headers
at their leisure.
