sal: match the defintions of SAL_MAX_SIZE and sal_Size
sal: match the defintions of SAL_MAX_SIZE and sal_Size

With 64-bit MSVC, sizeof(long) is 4 but sizeof(void*) is 8, so this
would select sal_uInt64 but SAL_MAX_UINT32.

This should make sizeof(sal_Size) the same as sizeof(size_t) on all
supported platforms, but still sal_Size maps to different integer
type (long vs. int) than size_t on 32-bit.
