[libcxx-commits] [libcxx] [libc++][test] Fix `is_always_lock_free` test (PR #105966)

[Stephan T. Lavavej via libcxx-commits]

https://github.com/StephanTLavavej created https://github.com/llvm/llvm-project/pull/105966

There were a couple of problems with this test added by #99570:

* It was named `is_always_lock_free.cpp` instead of `is_always_lock_free.pass.cpp`.
  + Noticed because the MSVC STL test harness looks for `MEOW.pass.cpp` specifically.
* It was using `std::same_as` without including `<concepts>`.
  + Noticed because MSVC's STL doesn't drag this in via other headers.
