983b2023 - [clang-tidy][NFC] Use mock header instead of #define NULL in tests (#188420)

[clang-tidy][NFC] Use mock header instead of #define NULL in tests (#188420) Since stddef.h in the mock headers of clang-tidy tests now provides `#define NULL 0L`, we can migrate manual `#define NULL` in these tests to standard `#include`s.
