The module std does not provide c-types in the global namespace. This
means all these types need to be fully qualified. This is a first step
to convert them by using sed.
Since this is an automated conversion other types like uint64_t are kept
as is.
Note that tests in the directory libcxx/test/std/depr/depr.c.headers
should not be converted automatically. This requires manual attention,
there some test require testing uint32_t in the global namespace. These
test should fail when using the std module, and pass when using the
std.compat module.
A similar issue occurs with atomic, atomic_uint32_t is specified as
using atomic_uint32_t = atomic<uint32_t>; // freestanding
So here too we need to keep the name in the global namespace in the
tests.

This avoids using an libc++ internal macro in our tests. This version
doesn't depend on the internal macro but redefines it.

Fix __bitop_unsigned_integer and rename to __libcpp_is_unsigned_integer.
There are only five unsigned integer types, so we should just list them out.
Also provide `__libcpp_is_signed_integer`, even though the Standard doesn't
consume that trait anywhere yet.
Notice that `concept uniform_random_bit_generator` is specifically specified
to rely on `concept unsigned_integral` and *not* `__is_unsigned_integer`.
Instantiating `std::ranges::sample` with a type `U` satisfying
`uniform_random_bit_generator` where `unsigned_integral<U::result_type>`
and not `__is_unsigned_integer<U::result_type>` is simply IFNDR.
Orthogonally, fix an undefined behavior in std::countr_zero(__uint128_t).
Orthogonally, improve tests for the <bit> manipulation functions.
It was these new tests that detected the bug in countr_zero.

Implements P1956: On the names of low-level bit manipulation functions.
Users may use older versions of libc++ or other standard libraries with the old names. In order to keep compatibility the old functions are kept, but marked as deprecated.
The patch also adds a new config macro `_LIBCPP_DEPRECATED_MSG`. Do you prefer a this is a separate patch?
