  Fix types of arm64 MSVC __readx18/__writex18 intrinsics

Using `L` for type `long` results in clang passing 64-bit integers to
these intrinsics on LP64 operating systems. This isn't correct as the
intrinsics accept 32-bit integers.

Use `N` instead of `L` so that 32-bit integers are passed to the
intrinsics on LP64 operating systems too. This is the same fix as the
following two commits:
