When testing MSVC's STL with C1XX, simulate a couple more compiler feature-test macros.
When testing MSVC's STL, simulate a few library feature-test macros.
test/std/atomics/atomics.lockfree/isalwayslockfree.pass.cpp
The vector_size attribute is a non-Standard extension that's supported by Clang and GCC,
but not C1XX. Therefore, guard this with `__has_attribute(vector_size)`.
Additionally, while these tests pass when MSVC's STL is compiled with Clang,
I don't consider this to be a supported scenario for our library,
so also guard this with defined(_LIBCPP_VERSION).
test/std/utilities/function.objects/func.not_fn/not_fn.pass.cpp
N4713 23.14.10 [func.not_fn]/1 depicts only `call_wrapper(call_wrapper&&) = default;`
and `call_wrapper(const call_wrapper&) = default;`. According to
15.8.2 [class.copy.assign]/2 and /4, this makes call_wrapper non-assignable.
Therefore, guard the assignability tests as libc++ specific.
Add a (void) cast to tolerate not_fn() being marked as nodiscard.

This warning "structure was padded due to alignment specifier" says
that the compiler is going to do exactly what you asked it to do.
It's triggered by the tests for over-aligned dynamic memory allocation.

Mark these tests as requiring 98/03/11/14 because 17 removed unary_function/binary_function.

This test doesn't need to be skipped in C++17 mode. Only the construction of
std::function from an allocator needs to be skipped in C++17 mode.

Define and use my_unary_function/my_binary_function to test the weak result type machinery

Now we can test C++17 strictly, without enabling removed features.

locale.codecvt.byname/ctor_char.pass.cpp:
This test used to use "en_US" as a plain string instead of using platform_support.
Need to fix this because MS STL expects "en-US" instead.
platform_support.h:
These are the legacy Windows locale names. Should use IETF tags instead.
I've also added en_US, since a test was using that as a locale string as well.
msvc_stdlib_force_include.hpp:
Remove _MSVC_STL_VER. The libraries will directly define _MSVC_STL_VERSION in the future.

This macro will instruct MSVC's STL to not warn about features that are deprecated in C++17,
as libcxx tests those features and uses them elsewhere.

This change works around a couple of bugs:
1. EDG doesn't like explicit constexpr in a derived class. This program:
struct Base {};
struct Derived : Base {
constexpr Derived() = default;
};
triggers "error: defaulted default constructor cannot be constexpr."
2. C1XX with /Za has no idea which constructor needs to be valid for copy elision.
The change also conditionally disables parts of the msvc_stdlib_force_include.hpp header that conflict with external configuration when _LIBCXX_IN_DEVCRT is defined.

_HAS_CXX17 indicates whether MSVC's STL is in C++17 mode.
In MSVC there's a distinction between CRT headers like stdlib.h and STL headers
like cstdlib. Only the STL headers drag in yvals.h, our internal STL-wide header
that defines internal macros like _HAS_CXX17.
_HAS_CXX17 is an MSVC STL library macro, unconditionally defined. We centralize
everything on this, because we have to ask different questions to determine
whether C1XX, EDG, or Clang is in 14 or 17 mode, and we additionally permit
users to override the detection in one way (it's okay to ask for 17 from the
compiler, but only 14 from the libs, at least for the moment; only noexcept
in the type system will give us a headache).
As this header is for testing MSVC's STL, we can assume _HAS_CXX17 is defined.
Fixes D32726.

libcxx's tests use various C Standard Library functions that have been
marked by MSVC's CRT as deprecated by Microsoft (not by ISO).
libcxx's usage is cromulent (just checking with decltype to see if the functions
are being dragged in by various headers as required by the Standard), so
defining _CRT_SECURE_NO_WARNINGS will silence the warnings in a targeted manner.
This needs to be defined before including any CRT headers.
Also, make this file prettier.
Fixes D29138.

Summary: This patch adjusts the newly added `msvc_stdlib_force_include.hpp` so that it also works when used with `clang++`.

No functional change; nothing includes this, instead our test harness
injects it via the /FI compiler option.
