Several components in libc++ aren't defending against overloaded
`operator,(T, Iter)` currently. Existing deleted overloads in
`test_iterators.h` are insufficient for such cases.

This PR adds corresponding deleted overloads with reversed order and
fixes these libc++ components.
- `piecewise_linear_distribution`'s iterator pair constructor,
- `piecewise_linear_distribution::param_type`'s iterator pair
constructor,
- `piecewise_constant_distribution`'s iterator pair constructor,
- `piecewise_constant_distribution::param_type`'s iterator pair
constructor,
- `money_get::do_get`,
- `money_put::do_put`, and
- `num_put::do_put`.

An older PR https://github.com/llvm/llvm-project/pull/102036 suggested
that LLVM libc declares `lgamma_r` as noexcept and is incompatible with
this redeclaration. However, I recently discovered that glibc also
declares the math functions to be noexcept under C++ mode.

This line usually don't cause issues because both the glibc and this
file are included as "system headers". According to [this
godbolt](https://godbolt.org/z/o7Wd9PP58), both GCC and clang ignore the
different exception specification between multiple declarations if they
are in system headers.

However, this seems not the case for NVCC/EDG, so a fix for this
redeclaration is still desirable. This patch proposes that we should
declare the function as noexcept under known libc integrations to keep
the declared function consistent.

This reverts commit c861fe8a71e64f3d2108c58147e7375cd9314521.

Unfortunately, this use of hidden visibility attributes causes
user-defined specializations of standard-library types to also be marked
hidden by default, which is incorrect. See discussion thread on #131156.

...and also reverts the follow-up commits:

Revert "[libc++] Add explicit ABI annotations to functions from the block runtime declared in <__functional/function.h> (#140592)"
This reverts commit 3e4c9dc299c35155934688184319d391b298fff7.

Revert "[libc++] Make ABI annotations explicit for windows-specific code (#140507)"
This reverts commit f73287e623a6c2e4a3485832bc3e10860cd26eb5.

Revert "[libc++][NFC] Replace a few "namespace std" with the correct macro (#140510)"
This reverts commit 1d411f27c769a32cb22ce50b9dc4421e34fd40dd.

This patch introduces `_LIBCPP_{BEGIN,END}_EXPLICIT_ABI_ANNOTATIONS`,
which allow us to have implicit annotations for most functions, and just
where it's not "hide_from_abi everything" we add explicit annotations.
This allows us to drop the `_LIBCPP_HIDE_FROM_ABI` macro from most
functions in libc++.

The need for `_LIBCPP_TEMPLATE_VIS` has been removed in #133233.

This is technically not necessary in most cases to prevent issues with ADL,
but let's be consistent. This allows us to remove the libcpp-qualify-declval
clang-tidy check, which is now enforced by the robust-against-adl clang-tidy check.

The variables are all `constexpr`, which implies `inline`. Since they
aren't `constexpr` in C++03 they're also not `inline` there. Because of
that we define them out-of-line currently. Instead we can use the C++17
extension of `inline` variables, which results in the same weak
definitions of the variables but without having all the boilerplate.

This is a follow-up to #89178. This updates the `<__config_site>`
macros.

`lgamma_r` is currently only available on GPU targets.
