ntdll: Use custom internal zero_bits_64 parameter format.

The zero_bits parameter can be a pointer mask on Win64 and WoW64 and it
was incorrectly truncated to 16bits in APCs. Testing shows that only the
leading zeroes are used in the mask, so we can safely use the 64 based
number of leading zeroes everywhere instead.
