When -fexperimental-library is passed, libc++ will now pick up the
appropriate __has_feature flag defined by Clang to enable the
experimental library features.
As a fly-by, also update the documentation for the various TSes.

In particular remove the ability to expel incomplete features from the
library at configure-time, since this can now be done through the
_LIBCPP_ENABLE_EXPERIMENTAL macro.
Also, never provide symbols related to incomplete features inside the
dylib, instead provide them in c++experimental.a (this changes the
symbols list, but not for any configuration that should have shipped).

a non-boolean type that's implicitly convertible to `bool`;
- checking that predicates and/or projections are invoked using
`std::invoke`.

This implements a not accepted LWG issue. Not doing so would require
integral types to use the handle class instead of being directly stored
in the basic_format_arg.
The previous code used `std::forward` in places where it wasn't required
by the Standard. These are now removed.
Implements:
- P2418R2 Add support for std::generator-like types to std::format
- LWG 3631 basic_format_arg(T&&) should use remove_cvref_t<T> throughout

- P1252 ("Ranges Design Cleanup") -- deprecate
`move_iterator::operator->` starting from C++20; add range comparisons
to the `<functional>` synopsis. This restores
`move_iterator::operator->` that was incorrectly deleted in D117656;
it's still defined in the latest draft, see
http://eel.is/c++draft/depr.move.iter.elem. Note that changes to
`*_result` types from 6.1 in the paper are no longer relevant now that
these types are aliases;
- P2106 ("Alternative wording for GB315 and GB316") -- add a few
`*_result` types to the synopsis in `<algorithm>` (some algorithms are
not implemented yet and thus some of the proposal still cannot be
marked as done);
Also mark already done issues as done (or as nothing to do):
- P2091 ("Fixing Issues With Range Access CPOs") was already implemented
(this patch adds tests for some ill-formed cases);
- LWG 3247 ("`ranges::iter_move` should perform ADL-only lookup of
`iter_move`") was already implemented;
- LWG 3300 ("Non-array ssize overload is underconstrained") doesn't
affect the implementation;
- LWG 3335 ("Resolve C++20 NB comments US 273 and GB 274") was already
implemented;
- LWG 3355 ("The memory algorithms should support move-only input
iterators introduced by P1207") was already implemented (except for
testing).

`__GCC_CONSTRUCTIVE_SIZE` and `__GCC_DESTRUCTIVE_SIZE` are available since GCC 12. I'm assuming clang will also implement these for compatability with libstdc++.
