ntdll: Implement zero_bits parameter in virtual alloc functions.
...
Use alloc_area.limit field to limit the search in reserved areas to the
desired memory range, or call find_free_area to get a pointer to a free
memory region which matches the zero_bits constraint, then mmap it with
MAP_FIXED flag.

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.
