SceneCacheFileFormat : Fix MSVC "warning C4003: not enough arguments for function-like macro invocation

- This came back after upgrading to MSVC 2019 and the latest USD. Despite USD trying to handle suppressing this warning, it seems to be stubborn and continues to be raised without further efforts.
- Using `ARCH_PRAGMA_*` is a bit cleaner and gracefully degrades to a no-op on non-Windows builds.
