librpc:ndr: Convert NDR flags types to enumerations
Using an enumeration rather than ‘uint32_t’ or ‘uint64_t’ means that debuggers such as gdb can now associate the flag constants with their respective types. This means that if you have an instance of these flags types, the debugger will show you the individual flags that make up the value rather than an inscrutable integer value.
