arch: xtensa: fix INT32_C macro to match int32_t type
INT32_C(x) is currently defined as x ## ll on Xtensa, which
produces a long long int constant. However, int32_t is
defined as long int on this architecture.
This mismatch can break C++ template overload resolution
and causes build failures in downstream projects such as PX4.
Fix the macro by using x ## l so INT32_C expands to the same
underlying type as int32_t.
