The device-only compilation path of vf_scale_cuda.h pulled in <stdint.h>
solely to obtain uint8_t for the CUdeviceptr typedef. On Windows-on-ARM
(aarch64 mingw) this drags in _mingw.h, whose ARM __prefetch intrinsic is
guarded by !__has_builtin(__prefetch). During clang's --cuda-device-only
pass __has_builtin has deferred/inconsistent semantics on the auxiliary
(host) target, so the guard mis-fires, the inline __prefetch definition is
emitted, and clang rejects it:
_mingw.h: error: definition of builtin function '__prefetch'
This broke the msys2-clangarm64 FATE slot once ffnvcodec (and thus the
nvcc-compiled CUDA filters) was enabled for aarch64 Windows.
uint8_t is unsigned char, so use that directly and drop the <stdint.h>
include. Device-only code should not depend on the host C runtime headers.
No functional or ABI change.
