Relocate the clock time getter to tests_common.h to make it easily reusable across test programs. This will be useful for the upcoming unit test framework. Context - why not placing it inside testutil.h?: The bench program links against the production-compiled library, not its own compiled version. Therefore, `gettime_i64()` cannot be moved to testutil.h, because testutil.h calls `secp256k1_pubkey_save()`, which exists only in the internal secp256k1.c and not in the public API.
