Context: https://github.com/llvm/llvm-project/pull/87017 - Add proxy header `libc/hdr/math_macros.h` that will: - include `<math.h>` in overlay mode, - include `"include/llvm-libc-macros/math-macros.h"` in full build mode. - Its corresponding CMake target `libc.hdr.math_macros` will only depend on `libc.include.math` and `libc.include.llvm-libc-macros.math_macros` in full build mode. - Replace all `#include "include/llvm-libc-macros/math-macros.h"` with `#include "hdr/math_macros.h"`. - Add dependency to `libc.hdr.math_macros` CMake target when using `add_fp_unittest`. - Update the remaining dependency. - Update bazel overlay: add `libc:hdr_math_macros` target, and replacing all dependency on `libc:llvm_libc_macros_math_macros` with `libc:hdr_math_macros`.
