[libc-commits] [libc] [libc][NFC] Remove libcpp include from atanf_test (PR #71449)

[via libc-commits]

https://github.com/michaelrj-google created https://github.com/llvm/llvm-project/pull/71449

The test for atanf used <initializer_list> to simplify iterating through
an array. This caused issues with the new features.h change by creating a
libcpp dependency in the test. This change moves the list to an array
variable, removing the need for that dependency.
